T-Mobile MMS settings on iPhone 4S (iOS6)

[CKohkah]

Hello,

I have an factory unlocked AT&T iPhone 4S that i gave to my wife to use on T-Mobile. I've followed all the tutorials on the web but i still can't get MMS to work.

I have successfully turned MMS on in the settings, but when I go to send a picture message, the sent status bar just hangs right before it finishes sending and fails.

I read something somewhere that I need to edit the plist, how do I do that without screwing the phone up?

Any advice would be greatly appreciated.

Hey bud,

Go to Safari on your iPhone, visit http://t-mobile.com/isetup. Then click "Accept" and it'll automatically update your iPhone to T-Mobile's network.

If you want to do it manually, here are the settings: http://support.t-mobile.com/docs/DOC-2383.
