* Most operators only allow fetching of MMS when accessing via a specific [http://en.wikipedia.org/wiki/Access_Point_Name APN]. To access this you would have to temporarily suspend your current 3G connection and switch over to this (is this correct? need someone with knowledge on this). On S60 you won't get dropped as long as you are on a 3G connection. | * Most operators only allow fetching of MMS when accessing via a specific [http://en.wikipedia.org/wiki/Access_Point_Name APN].

* If the user only got access to GPRS the current connection (if in-use) have to to be temporarily suspended while fetching the MMS. This should be doable by doing a "Deffered Retrieval". <ref>[http://www.openmobilealliance.org/Technical/release_program/docs/CopyrightClick.aspx?pck=MMS&file=V1_3-20080128-C/OMA-TS-MMS-CTR-V1_3-20080128-C.pdf Figure 7.

Discussion at [[http://wiki.maemo.org/Mms_implemention_conversation#Technical Mms_implemention_conversation#Technical]] The following is based on that conversation: |
** The problem here is routing specific data to the specific connection. While this is possible with some clever routes, this does raise the problem with operators having the same gateway for both GPRS and MMS connections, which might lead to a collision (if both they are indeed the same gateway, it should be no problem just getting the MMS over the current connection?). | ** The problem here is routing specific data to the specific connection.

** One possibility is to tag the appropiate packets with iptables and then sent to a different routing table. | ** One possibility is to tag the appropiate packets with iptables and then sent to a different routing table. | ||

* The functionality to handle the above problem is in linux-2.6.30+ (Fremantle runs 2.6.28) so if there is a future kernel upgrade, it should be possible to implement full MMS support. [http://talk.maemo.org/showthread.php?p=349859#post349859 See this talk-post.] Alternative would be to backport the networking namespace to 2.6.28. | * The functionality to handle the above problem is in linux-2.6.30+ (Fremantle runs 2.6.28) so if there is a future kernel upgrade, it should be possible to implement full MMS support.
