Updating Iphone 3g from Fw3.0 tp 3.1.2
it might sound noobish but i have some doubts regarding updating my iphone 3g.
currently my iphone is on FW3.0 and baseband or modem firmware 4.0.xx
anyways here are few questions
1. does upgrading my firmware to 3.1.2 also upgrades my baseband or modem fw?
2. Is there any major differences b/w both fw i.e. 3.0 and 3.1.2.
3. What do u suggest should i upgrade or leave as it is.
Why i was thinking to upgrade coz some application werent working on current fw.
Waiting for your replies.
