Alright guys, So I'm on a family unlimited texting plan. I couldn't get MMS to work on my phone for the life of me! I finally decided to try doing that mediaNet trick that people were talking about. But what triggered me to do it, was an article I was reading on gizmodo. I was able to get MMS working on my phone and 2 other phones (friends with 3.0).
1. Put your sim card into another phone with MMS capabilites. Then text and call people for about 5-10min
2. Go to

Follow the on screen instruction...put in your cell phone number blah blah blah
(if it says this phone is not supported, its cause the system is still recognizing the iPhone. So just log into your account on AT&T and manually change the phone. Give it some time and try again.)
3. Once it sends you the text to your phone continue following the on screen instructions (only 2 more lol)
4. Give it some time to work...because it will not work INSTANTLY but if you give it a little bit maybe like an hour or so it should work. Just be patient, once again it will not work immediatly after...you have to give it some time. (for my 2 friends it took between 30min- 1 hour)
Also I DID NOT USE MODIFIED .IPCC files on my friends phones, but I did use it on mine because I wanted the tethering.
HOPEFULLY THIS WORKS FOR MOST OF YOU PEOPLE...especially people with the family unlimited texting.
