Ive got a 2g on 3.1.2 & used "Native MMS iPhone 2G" app from cydia to enable the mms (as described here) Enable MMS on iPhone 2G 3.1.2 Firmware | Redmond Pie
I now have the camera button under my messages but am unable to change my carrier settings under Cellular Data Network..... Settings –> General –> Network –> Cellular Data Network!!! It doesnt show up, is there a way to make it visible in order to change it or maybe instructions on how to ssh into it & change to the correct carrier settings for AT&T?
Any help greatly appreciated
