I have done the hack that you download from Cydia where it adds MMS to the iPhone 2G, but I only get so far. After reinstalling it twice, I finally got the Settings>General>Network>Cellular Data Network menu to show up, as well as the camera icon in the messages and stuff. What I need now is the AT&T settings, I tried downloading those custom ones but they don't seem to work. I currently have the iPhone data plan bundled with 200 messages [my family unlimited messaging plan overlaps this]. Am I supposed to change this? I used to have the smartphone plan but when my iPhone said it couldn't connect, obviously, I figured that was the reason it couldn't send an MMS. So basically I need the AT&T settings under the Cellular Data Network menu, and any plan changes I'm supposed to make. Thanks!
