MMS Doesn't Work on iPhone 4

[BzowK]

Hello All-

My wife and I both have iPhone 4s on AT&Ts network. they are both running iOs 4.1 which was jailbroken with redsn0w.

Currently, neither phone's MMS works. When trying to send an MMS, the progress bar gets to about 95%, then stops. After a respiring, it shows a red exclamation beside the message. FaceTime does work, though.

I've googles all kinds of stuff but can't find a fix. Most posts I've found refer to MMS & FaceTime not working on unlocked phones on T-Mobile but this is not the case. I tried these fixes anyways, but they did not work. My carrier settings are 8.0.

Please suggest what you think may be wrong. Thanks!

Try a Reset Network Settings. If that doesn't work call AT&T customer care tomorrow and make sure the account is set up right.
