The N900, unlike previous Nokia internet tablets has a phone module.

[edit] Hardware

The phone is a 2G/3G modem, with quadband GSM, and several bands of 3G. It may not have the required band for 3G in your country, for example, only one US carrier (T-Mobile) and only one Canadian carrier (Wind Mobile) support 3G on the N900.

The phone module controls the GPS, and contains software to generate locations.

[edit] Software

For the GPS, liblocation is used.

The modem can be accessed 'directly' - through pnatd.

This thread on the maemo-developer mailing list gives some examples of using pnatd - but it is not a reference guide.

ICD is the daemon that deals with internet connectivity, including managing data connections to the phone.

More documentation on ICD is found here.

SMSs are stored using eventlogger
