MMS on 4.0.1 w/ 3GS

[kidwithdimples]

For some reasons I can't receive or send any MMS anymore.

Is there a fix for this? Do I have to reset my Network Settings?

Did you install anything lately?

A network reset wouldn't hurt.

Go to Settings > Messages and make sure MMS is switched to ON.

Didn't install anything new.

Well I might've installed TMOBILE MMS FIX 4.0.1 from Cydia.

Go to Settings > Messages and make sure MMS is switched to ON.

It's turned on.
