MMS blocked by ATT on 2G. :(
I have tried everything to get MMS working. I have made the "camera icon" visible on 3.0, 3.1.2 and tried MANY settings. After a long time of failing I finally called ATT. I tried putting my sim in another phone and it wouldnt work, so I called ATT, provisioned the other phone (razr) and it sent mms perfectly. I then popped it back into my phone and got "no cellular data connection" or some error like that. Until I called them with my IMEI number to "re-enable" my iphone, it would not do much.
So, I have concluded that ATT is blocking mms on the 2g and there will be NO WAY to make it work on the 2G on the ATT network. Period.
