SMSCON

'''Please Note: Update for 0.9.10++ is in progress for this page but will take another couple of days. The information up to, not including "Usage" is now updated already. The remaining parts is being worked on'''. -- yablacky 23:24, 30 December 2011 (UTC).

SMSCON provides complete control of your N900 by sending SMS commands to it. Other methods are supported as well - we come this is later - but SMS is easiest way and it is the reason why this app is named SMSCON.

Remote controlling your phone is particularly handy in case you cannot find it, for example if it has been lost or even stolen. The first approach to find the phone is giving it a usual phone call awaiting to hear it ringing somewhere in your coat-pocket or the like. If this doesn't help, SMSCON comes into play. SMSCON can't guarantee that you will find your phone again, but it will provide the maximum chance to recover it. If this application ever helps you to recover your phone please tell the story on Maemo.org! The best way is of course to never lose your phone or let it get stolen...

SMSCON Editor is a GUI helper application to configure and even test SMSCON operation. We recommend normal users of the phone to use SMSCON Editor.

Configuring SMSCON without SMSCON Editor is possible but you need some experience in unix command line. As almost ever, the command line offers maximum possibilities to adjust the application to your own needs.

WARNING: This application can send (multiple) SMS messages automatically (in the background). Be aware that SMS sending is not free and it's costs depends on the used telephone subscription with your Nokia device. Sending many SMS might be a minor problem for those having a SMS-flat-rate...

Features

 * Autoloads at boot. This ensures that SMSCON is active (that means is listening for commands) even after device (re)boot. Autoload is enabled by default during installation of a smscon package.
 * Create and keep a log file on the device. The log file can be queried remotely by SMS command as well as locally via command line.
 * Looking for commands in received SMS messages and/or by polling a remote command server (maintained by you, the user).
 * Sending notifications, responses and query results by SMS and/or by EMAIL.
 * Detect SIM card change. It will send a notification containing the new SIM card's phone number, IMSI code & telecom operator name. This scenario happens if somebody has stolen your phone and replaces your SIM by his/hers own SIM.
 * Optionally unlock the phone on detection of SIM card change. -- Why unlocking? Well, unlocking makes sense when regular phone owner is more interested on finding the actual device than as keeping its private/sensitive phone data protected/locked. A locked phone prevents even to enter the SIM card PIN. Consequently telephone functions do not work either. This is very secure but makes it almost impossible to contact the phone after booting with unknown SIM card installed. Note that a finder may remove the SD-memory card to read its content.
 * Lock the phone by command. Nobody can use your locked phone until it receives an unlock command.
 * Send notification about current GPS location coordinates via SMS message and/or EMAIL. Those EMAIL have even attached a GoogleMaps picture with your phone's location on it.
 * Track the phone's GPS location and location changes by let it automatically send repeated notifications in a selectable time interval.
 * Reboot the phone. This is just possible but not generally recommended: if your SIM card has a lock code and nobody enters it correctly, it would boot but could not connect to GPRS network.
 * Shutdown the phone. Also just possible but not generally recommended.
 * Open a (reverse-)SSH connection to your own (home-)server to control the phone at command-line level from your own home (or any other) computer.
 * Let front camera take pictures and send them via email notification. With a some luck you may see where your phone is or who is using it.
 * Detect and send notification about the current battery charge level and status.
 * Let the phone make a voice call to your controlling phone. Once the call is established you can listen where your phone is.
 * Detect keyboard slider movement and send notification about that. Keyboard usage might indicate that somebody has found your phone.
 * Let the phone send all recognized SMS commands to you, e.g. if you've forgotten them. This way you need just to remember the code of one single command (the COM_CHECK command).
 * Run a pre- and user-defined shell script to start other programs, delete files etc. May be used to wipe out sensitive data from phone. Direct wipe commands are not provided by SMSCON. Writing (and testing) a script doing so is at your own risk.
 * Run directly a shell command through SMS message sending where result is immediately reported.
 * Optionally turn the phone silent after SMSCON receives a known command.
 * Automatically and optionally send notification about the current battery status when SMSCON receives a known command.
 * Use multiple SIM cards.
 * Play a pre- and user-defined sound file (only WAV supported). May be used instead of just let the phone ring and let it say a special message.
 * Can kill & restart the background daemon by SMS command. This might be preferred operation instead of rebooting the phone.
 * Send notifications if background daemon crashes. Should this ever happen, you're encouraged to forward them to the SMSCON developer team (make a bug report).

Files
This section is a description of what you get when installing SMSCON. This is not a must-read when getting in touch with SMSCON for the first time.

If not otherwise stated, the location of all files mentioned in this section is.

SMSCON is a command line application whose executables parts are mainly:
 * , the command-line control part and
 * the daemon part, running in the background.

SMSCON is highly configurable and all the settings are stored in the  file. Many settings are stored encrypted, so - from version 0.9.3 on - do not edit the file directly. See below for how to change settings.

Files intended to be edited by user directly

 * , a unix shell script to extend SMSCON functionality. This script is intended to be edited by the gentle user. The installation of SMSCON provides a file with some non-destructive example code. SMSCON executes the script in the background with root-rights when receiving a COM_CUSTOM command. You need to be root to change.


 * , a WAV-format sound file. SMSCON plays the sound when receiving a COM_ALARM command. A special sound file (suitable to all languages) is provided by default. You're encuraged to replace it by your own sound. Write it to . Note: currently only WAV sound is supported by SMSCON.

Files used internally
None of these files are intended to be viewed or even edited by a user directly. So don't do it. Use SMSCON commands to view and change them in a consistent way:


 * application program files and libraries
 * several log files
 * internal configuration files
 * temporary files to hold camera pictures, google maps etc.
 * last not least, there are some internal files not stored in.

Names of internal files are not mentioned here by design. They are matter to change without notice as is the existence of this files itself.

Files from other packages
The installation of SMSCON via application manager ("HAM") usually installs other software packages implicitly. They are also de-installed on SMSCON's de-installation (via HAM) in case they are no longer referenced otherwise.

Besides python2.5 this is: python-crypto python-gobject python-location python-dbus pexpect gstreamer-tools openssh-client openssh-server alsa-utils  /* NEEDED IN >= 0.8.1 */

As said above, regular use of SMSCON does not require knowledge of files nor packages used.

Installation
The SMSCON & SMSCON Editor packages can be found in the Extras repository and can be installed using the Application Manager (HAM).

Always install the latest stable version on your phone; previous version can have bugs and have less functionality!

On very first installation, SMSCON generates


 * a default settings file with all the user settings of SMSCON.
 * an IMSI database to store IMSI numbers of SIM cards allowed. Other SIM cards will cause detection of SIM card change and lock of the device on boot.
 * a default  file with example code for COM_CUSTOM command.
 * a default  file for COM_ALARM command.
 * a SMSCON logfile.

On installation of update versions (since 0.9.*), SMSCON


 * updates the settings file to disable obsolete settings
 * updates the settings file to add new settings
 * leaves IMSI database untouched
 * leaves  file untouched
 * leaves  file untouched
 * tries to repair previous SMSCON installation.
 * adds entries to SMSCON logfile.

Before using SMSCON the first time
It is highly recommended to review user settings and adjust them to your needs.

We recommend use of SMSCON Editor. Hackers may use the  command on unix command line.

The absolute minimum is to set up the so-called master number. This is a phone number, namely the phone number of the main controlling phone. It can but should not be number of your N900 being controlled - this would be nonsense. Best choice is to use the number of a second phone in your phone-portfolio. But the number of your boy- or girlfriend's phone also does. No matter if that is a N900 as well.

Controlling your N900 is not restricted to the master number's phone. Any phone in the world can be used to send controlling SMS to your N900 and SMSCON sends SMS responses to it. One role of master numers's phone is to receive a blind copy of all SMS that SMSCON sends to other phones.

This is handy in case your N900 got lost and someone else concurrently tries to controll it. Your master number's phone will always be notified.

Another role of master number comes into play if you start to controll your N900 using different methods than SMS. We come to that later.

Setting the master number

 * The most easy and typo-aware way to set the master number is using SMSCON Editor version 0.9.8 or higher and it goes like this:


 * 1) Open SMSCON Editor and ensure daemon runs.
 * 2) Quit SMSCON Editor.
 * 3) Send a SMS from the potential controlling phone to your N900. The message text must be   no more no less (provided all settings are default yet - otherwise use your own code).
 * 4) Wait until the SMS was received by your N900.
 * 5) Again open SMSCON Editor go to "General" settings page.
 * 6) If the SMS was recognized by SMSCON, then the "last sender" field shows the phone number of the controlling phone. Enter this number exactly as shown in the "master number" field above.
 * 7) Quit SMSCON Editor

Open SMSCON Editor go to "General" settings page, fill in "master number" field. Hackers may do this: $ smscon -set MASTERNUMBER +xxyyyyyyyyyy
 * The master number can be set directly:

All phone numbers should be entered with country prefix. Not only ensures this that SMS are send successfully regardless where your phone actually is located. It further is essential to make phone numbers compareable.

Setting other options

 * if you want to use the SSH connection feature of SMSCON (i.e. 'Remoteon' and 'Remoteoff' commands), you also need a fixed IP address on your preconfigured remote server for the SSH (default port 22) connection.


 * to be continued...

Usage
SMSCON is triggered by a SMS message with a predefined known command and then will execute the task in the background. If so it will send a reply SMS or email with the information.

Commands
The (default) predefined commands are: Nokia-N900:~# smscon -sms COM_CHECK        = 'Check' COM_REBOOT       = 'Reboot' COM_POWEROFF     = 'Poweroff' COM_POWER        = 'Power' COM_LOCATION     = 'Location' COM_REMOTEON     = 'Remoteon' COM_REMOTEOFF    = 'Remoteoff' COM_CAMERA       = 'Camera' COM_CALL         = 'Call' COM_LOCK         = 'Lock' COM_UNLOCK       = 'Unlock' COM_TRACKON      = 'Trackon' COM_TRACKOFF     = 'Trackoff' COM_CUSTOM       = 'Script' COM_SHELL        = 'uptime >> /tmp/shell_log' COM_ALARM        = 'Alarm'   /* NEW IN 0.8.1 */ COM_RESTART      = 'Restart'  /* NEW IN 0.8.1 */

NOTE: These commands can be changed using the SMSCON Editor and also at the command-line with the  command (see SMSCON command-line options).


 * When sending 'Check' to you phone it sends one or more SMS messages with all the available SMSCON commands.
 * Sending 'Reboot' it will reboot your phone.
 * Sending 'Poweroff' is will shutdown your phone.
 * Sending 'Location' is will send it's current position by SMS or EMAIL (or both).
 * Sending 'Remoteon' it will enable the SSH connection to your (home-)server. 'Remoteoff' will kill the connection.
 * Sending 'Camera' will send a frontcam picture by email.
 * Sending 'Call' will call you.
 * Sending 'Lock' will lock the device, so nobody can use your phone. 'Unlock' will remove the device lock.
 * Sending 'Trackon' will continiously send SMS or email (or both) with location of the device & 'Trackoff' will disable this.
 * Sending 'Script' will run a predefined by user shell script.
 * Sending 'uptime >> /tmp/shell_log' (an example shell command) will exectute the shell command on your phone (no checks & output are returned!)
 * Sending 'Alarm' will play once a user selectable file (only WAV format and must be named  in   directory)   NEW IN 0.8.1
 * Sending 'Restart' will kill the smscon_daemon and restart it.  NEW IN 0.8.1

USAGE EXAMPLE:
 * To trigger any of the commands the phone should receive an SMS having in the subject its defined name. E.g. to trigger the  command the phone should receive:.
 * The commands can use spaces in them and can be altered in a command only you know what it is and what it means.
 * the alarm audio file (only WAV format and must be named ) must be placed, if the option is used, in  .   NEW IN 0.8.1
 * To trigger any of the commands by a remote file on your own server (when option ENABLECHECKHOST is enabled), the file only must contain one of the following values from 00, 01 to 17 or -1:

01 = COM_CHECK 02 = COM_REBOOT 03 = COM_POWEROFF 04 = COM_POWER 05 = COM_LOCATION 06 = COM_REMOTEON 07 = COM_REMOTEOFF 08 = COM_CAMERA 09 = COM_CALL 10 = COM_LOCK 11 = COM_UNLOCK 12 = COM_TRACKON 13 = COM_TRACKOFF 14 = COM_CUSTOM 15 = COM_SHELL 16 = COM_ALARM 17 = COM_RESTART

When value is 00 smscon_daemon will not be activated (normal situation) and when value is -1 the smscon_daemon will be restarted. It is of course necessary that the file on your server publically can be reached by your Nokia device, otherwise it won't work. Check this! The default CHECKTIME is 15 minutes (this can be changed by user), so when you change the content of your file it can take a maximum CHECKTIME minutes to execute the command. NEW IN 0.8.1

The user editable settings of the  file:


 * 1) smscon user settings (v0.8.1)
 * 2) (DO NOT edit the encrypted user settings below, use SMSCON-editor or SMSCON!)

Options
The available command-line options for SMSCON are: Nokia-N900:~# smscon -help

smscon v0.8.1 - Nokia N900 remote control utility
Options: -start            : start smscon_daemon -restart          : stop & restart smscon_daemon -stop             : stop smscon_daemon -status           : get smscon_daemon status -log              : show log file -del log          : erase log file -sms              : show SMS commands -set name "value" : set user setting (name = "value") -config           : show config file -script           : show script file -boot             : start smscon_daemon at device boot -unboot           : remove start of smscon_daemon at device boot -add imsi         : add current IMSI code to code file -remove imsi      : remove current IMSI code from code file -help             : this help menu Special options (normally not needed!): -reset            : factory default (delete boot, config, code & script file) -imsi             : show IMSI code file -del imsi         : delete code file -init             : create default config & script file -del config       : delete config file -del script       : delete script file

After installation
After installation  will generate a new configuration file  which you *must* edit to your own needs (i.e. change all xxxxxxx's). To edit this use SMSCON Editor, which will assist in the configuration setup, or use the command-line  option. Also a shell script file will be generated were the user can predefine shell commands to run other programs, delete files etc.

SMSCON will also be installed to autoload at boot, this can be disabled with the command-line command  and re-enabled by   or with SMSCON Editor.

The first time you start SMSCON it loads the configured user settings file and is now active. then stores your valid IMSI code in a file if the file doesn't exist.

When later a new SIM card is inserted the new IMSI code is verified with the code in the stored  file. This is how the "SIM card change" will be detected.

Nokia-N900:~# smscon -start smscon_daemon started.

All user action and behavior of  will be logged in the log file (at  ):

Nokia-N900:~# smscon -log SMSCON INFO: - smscon_daemon is started & running - DAEMON INFO: successfully loaded "smscon_config" file DAEMON INFO: reading 1 valid IMSI code from "smscon_code" file DAEMON INFO: authorized IMSI code found DAEMON INFO: smscon auto-loads at boot

When having trouble with SMSCON always check the  file!

Remote SSH connection
When the (reverse-)SSH connection is made (default command 'Remoteon' / 'Remoteoff') you can from the server side (your own server) connect to your Nokia device with the following command:

ssh -p 8080 localhost -l root

0.9.11-2 Development'''
Availability: Extras-devel

Changelog FIX: Fixed repeated resending of sms or email in almost zero-time intervals in case resend-time interval was configured to less than 1 minute. ADD: Anonymized log files. Can be used to post logs in bug reports etc. Works like this: Logfile shown by command "smscon -log" is now anonymized by default (phone numbers, host names, IP-addresses) IMPORTANT NOTE(1): Anonymizing takes place with ABSOLUTELY NO guarantee! IMPORTANT NOTE(2): It is NOT A BUG if there is too much or "wrong" anonymizing. If new option "-pw password" was seen on command line before -log, then logfile is shown un-anonymized as before. And of course a super user has not limits anyway. CHANGE: Logfile is no longer readable by normal user. FIX(MINOR): Fixed typos and added more comments.

0.9.10-1
Changelog FIX: If called in user mode, prevent -export or -export! option to create/write files that user has no permissin to create or write. FIX: Fix crash: TypeError: can only concatenate tuple (not "list") to tuple

0.9.9-1
Changelog CHANGE: Deamon does no longer need to restart for switching between test mode and normal operation mode. FIX: Daemon now reads test command requests from a named pipe and works them off sequentially (allows to quickly start several tests in a short time). FIX: Fixed that COM_REMOTEOFF command did not work. FIX: Fixed daemon crash ("need more than 3 values to unpack") FIX (AGAIN): Force using busybox ps-command to ensure that process information like PID is at expected place.

0.9.8-1
Changelog FIX: Fixed problems with daemon process ids on devices with extended "ps" command installed. This bug might prevent power users from using smscon. So this fix is reason for early release of new version. FIX: Fixed interchanged message parameters in smscon -init! command output. ADD: Added usage hints to initial smscon_script file (minor change).

0.9.7-1
Changelog FIX: Send battery status notification if charge is below 10% AND discharging (not OR discharning). If devices can't tell change/discharge status; discharge is assumed. FIX: Don't check for bootloader if in test mode. FIX: Wrong error message that daemon did not start on devices with extended "ps" command installed.

0.9.3-1
Changelog

REFACTURING: * Extracted common code to a library (smsconlib.py) which is now used by smscon_daemon, smscon control program and smscon-editor. * Added a lot of code comments. * Encapsulated many code into classes. E.g. the complete encyption stuff is now transparent to smscon control program and smsmcon editor. * Restructured code, written new and renamed a lot of old stuff. * Moved code from files "smscon" and "smscon_daemon" to pure python-modules (smscon_master.py and smscon_service.py respectively). The original files are now just jackets calling main in associated python module. This allows to compile the modules and hiding source code. NEW:   Encryption now uses salt (formerly encrypted data can be read). FIX:   Encryption does no longer fail on text ending with curly open brace. NEW:   "MASTERNUMBER" concept: A SMS number stored in the config file that  does NOT change due to SMS commands like "SENDERNUMBER" does. Each SMS is send to both (only once if they are the same numbers, of course). SMS replies to commands which are not introduced by SMS (e.g. via CHECKHOST) are sent to the MASTERNUMBER only. On upgrading, the default MASTERNUMBER is set to the current SENDERNUMBER. NEW:   "COM_CUSTOMLOG" command: A SMS command to retreive the output of the last "COM_CUSTOM" command. Will be sent via email only - would send too much SMS... NEW:    "COM_LOG" command: A SMS command to retreive the smscon.log file. Will be sent via email only - would send too much SMS... NEW:    The output of "COM_SHELL" SMS command is now sent as a command reply. You may have to remove output redirections from your shell command to get non-empty reply. NEW:   "SMS_PARTS_LIMIT": A number to limit the number of single SMS that would otherwise be generated to send a too long SMS message. Zero means no limit. NEW:   "LOG_TIMEFORMAT": Format to be used in time stamps of SMS and EMAIL messages. NEW:   "SMS_COMPREFIX" and "SMS_COMSUFFIX": Instead of explicitly define all your SMS control commands (COM_xxx) to start with a unique prefix and/or suffix, you might now separately define a prefix and/or suffix that is implicitely used. While "SMS_COMPREFIX" and "SMS_COMSUFFIX" are empty, all your commands do as in older versions. Advantage of using "SMS_COMPREFIX" and "SMS_COMSUFFIX": * Prefix and suffix can be changed easyly while embedded COM_xxx remain unchanged. * Prefix and suffix apply to COM_SHELL command as well. Example: With the configuration set to: COM_SHELL=uptime SMS_COMPREFIX=aaa. SMS_COMSUFFIX=.bbb The recognized SMS command to execute the shell command "uptime" is: aaa.uptime.bbb FIX:   It is no longer possible to define two SMS commands as the same string except the empty string, which means to disable that command being given via SMS. FIX:   SMS command recognition is no longer restricted to ASCII characters. The complete GSM 7 bit default alphabet may be used now (but not unicode). This gives you a greather variete of chars to use for your SMS commands. NEW:   The config file will now upgrade automagically from any previous version. New options are set to their default, obsolete options are commented out. NEW:   New function to export and import settings to/from arbitrary file. (see smscon -export and -import options). smscon editor makes now use of this functions to retrieve a and deploy editable configuration. NEW:   The smscon_daemon does no longer need to be restarted explicitly if smscon changes a setting. The daemon detects changes automagically and will read and apply the new configuration automatically. NEW:   The smscon_daemon now maintains a "last known good" configuration and uses that as a fallback in case the "official" configuration of smscon can't properly loaded by the daemon. NEW:   Camera picture and GSP Location requests do no longer force unconditional switching to GPRS network connection. The current connection will be used if the internet is reachable. Should a GPRS connection be required to reach internet, the GPRS connection is established but the previous network is re-activated after picture and/or location has been replied. NEW:   A LOGGER is now used wherever possible. So the smscon.log file becomes really interesting. NEW:   The "CHECKHOST" URL is now extended by "?LASTMCD=nn&CHECKTIME=minutes" which will allow the URL being a script that may use this information. CHANGE: "CHECKHOST" now works more clear as follows: While polling for commands, a command is executed once, if it differs from the last polled command. The last polled command is initialized to "-1" on daemon start. Code "-1" is "restart daemon" and this obviously is what happened on daemon start. Code "17" (COM_RESTART) is deprecated as a CHECKHOST command. Since it is different from "-1" it may restart the daemon repeatedly. Use code "-1" to restart the daemon via CHECKHOST instead. Of course, before a change to code "-1" is recognized by the daemon, you must have give it a different command code. If in doubt use "01" (COM_CHECK) because it gives you feedback that the command has been seen. CHANGE: "CHECKTIME" may now be a float to specify fractional parts of a minute: 0.25 is 15 seconds. NEW:   The "CHECKHOST" URL may now have a protocol prefix and it may be different from "http://". If the URL has no protocol prefix, then "http://" is supplied as default as in former versions (e.g. your config file remains valid in this point as well). NEW:   The battery status is logged before a command is about to be executed. NEW:   "REMOTELISTENIP", "REMOTELISTENPORT" and "REMOTE2LOCALPORT": These settings give you greather flexibility of setting up a tunnel to remote control your phone via a reverse ssh-connection: Use "REMOTELISTENIP" and "REMOTELISTENPORT" to define the tunnel entry maintained by the remote ssh-server (which must be setup to allow setting LISTENIP and PORT this way). "REMOTELISTENPORT" defaults to 8080 and "REMOTELISTENIP" defaults to "localhost" as in former versions. With these defaults you must be logged in at the ssh-server to start a remote control connection of your phone. While setting up "REMOTELISTENIP" you may even control the phone from somewhere else (in which case the ssh-server act as a proxy or relay). On the tunnel exit side, which is on your phone, the "REMOTE2LOCALPORT" is the port number where your phone's ssh-daemon is listening (usually 22). CHANGE: The "smscon -devconfig" command now requires a password to show the uncrypted configuration. The MASTERNUMBER is the password. NEW:   "RESENDMAXTRY": This option defines the maximum number of message re-send tries. Applies to SMS and EMAIL as well. (0=no limit) On configuration upgrade this is initialized to 10. NEW:   smscon now has a -sendsms option to send SMS immediately. Despite being a nice feature by itself, it makes smscon editor independent from smssend program which requires an extra package. NEW:   smscon now allows all options to start with the usual double dash as well.

Future development ideas
Feel free to add requests below.


 * Add a provision for SMS reception without the UI being notified (so that SMSCON control is silent).
 * saving all  user variables in gconf database. No need for   file anymore. (WONT IMPLEMENT)
 * add setting for user's country mobile number prefix.
 * add setting for alternative number (where alternative is a number sent a command and does not match the default) and option to choose where reply should be send, i.e. default number, alternative or both. Default number should not be replaced.
 * add setting to choose the default internet connection (WLAN, GPRS, or ANY). At the moment hardcoded to GPRS. (WONT FIX)
 * when the "Camera" command is sent, the process should wait for keyboard action to capture a picture and send the mail. In that way, there will be more chances to get better face portrait of the "new" user.
 * Add the ability to run custom commands (very useful, but especially needed to delete sensitive data from the phone). (IMPLEMENTED IN 0.5-9 / 0.7-1)
 * Add the ability to turn silent mode on. (IMPLEMENTED IN 0.7-1)
 * Application must be included in the ROM itself so that it cannot be removed. (CAN'T BE IMPLEMENTED)
 * Add a password so that no one else but the legitimate user can send an SMS to the phone and see where the phone is. (INFO: use the prefix option in the Editor application)
 * Auto remove the received SMS from conversations.
 * Disable PhoneSpeakerSwitch on receipt of 'call' command.
 * EmailCON: check an specified email inbox, reading it with the program itself and not the built in default mail prog, at a given frequency, paying attention to commands written in the subject and/or body, accepting all the commands that are accepted via SMS. (WONT IMPLEMENT)
 * Improve handling of front camera to reduce the odds of crappy or plain blank black pictures being taken. (CAN'T BE IMPLEMENTED)
 * When in "stolen" mode, replace the front cam "recording" LED pattern with a on-lighting pattern for stealthiness.
 * Email, or post online somewhere you choose, any new photography taken with the main camera, geotagging whenever possible, preferably without showing any signs it's happening (if possible with an option to re-dimension the picture before sending).
 * give the smscon_script executable privileges during installation (BluesLee, Saturn)
 * exclude the smscon_script from the initialisation loop (BluesLee, Saturn)

Testers needed
Please test this software, I like to hear if it works for you or not. Please post on forum. I only can test the software with two Vodafone SIM cards from The Netherlands, I want to know if it also works with other cards and networks in other countries...
