I'm running iPhone 3GS 3.1.2 unlocked via blackra1n on T-Mobile USA. My MMS has worked up until recently. I have restored and that did not help. The settings I have are: wap.voicestream.com mmsc: 126.96.36.199/servlets/mms mms proxy: 188.8.131.52:8080 Everything else is blank. Also, I'm on the old $20 grandfathered internet so my APN (at the very top of the screen) is internet2.voicestream.com Please help. Thank you. (I received a MMS just now and it says, "The media content was not included due to a picture resolution or message size restriction.") Keep in mind I was able to MMS fine send/receive to the same person a few weeks ago.
