Have a prepaid iPhone 3GS on telecom's XT and I cannot get the MMS to work since I have uptated to 4.0.2
I have entered all the carrier settings properly and have triple checked this. I read that some other people have been having trouble with this and that upgrading their sim to a version 3 sim fixed this. However I have just gone and had my sim card replaced at Telecom and it still does not work. It starts sending the MMS and then it comes up with the little red exclamation mark and says message send failure
Any Idea's?
