AT&T is promising MMS on September 25, along with a software update to enable it. Sounds like iPhone 3.1 to us. Show it off at the September 9 Music Event along with the third generation iPod touch, then release it a couple weeks later to coincide with MMS?

WhenWillApple reports that AT&T MMS is already working for them in Florida under iPhone 3.1 Beta 3. and while it might just be another random network test, could it also be a sign of what's to come?

Anyone else rocking AT&T MMS on iPhone 3.1 Beta 3? Say where and when in the comments!
