MMS Fix for iPhone 4 (GSM) on T-Mobile USA
I finally unlocked my iPhone 4 (GSM) and got it to work on T-Mobile's network. So far, voice, SMS, and data (EDGE) are working fine. The only gripe I have is the MMS. I can send but I CAN'T RECEIVE. I've called T-Mobile a dozen times but because the iPhone 4 isn't an official device for them, they are unable to fully troubleshoot the issue.
I've read several posts on the forums and it seems everybody thinks the MMS issue can be solved by altering the APN settings in the "Cellular Data Network" menu. I have tried every combination of APN settings and IT DOESN'T SOLVE THE ISSUE.
Here is the skinny:
PC OS - Windows 7 (32-bit)
Model - iPhone 4 16GB (GSM)
iOS - 4.3.5 (8L1)
Modem Firmware - 4.10.01
Jailbreak - NO JAILBREAK
Carrier - T-Mobile USA (postpaid)
I have a feeling that something more internal needs to be "tweaked" to make MMS work on T-Mobile USA. Please help! Thanks :)
