What a suprise. Decided to try it <again> - this time MMS works! I come from 2.2.1 -> 3.0b2.
I can send MMS/Receive MMS without any errors nor did I have to modify any carrier .plists!
Update:
In USA, AT&T 3G , with iPhone 3G, firmware 3.0b2 - 2.2.1 upgrade to 3.0b2 with complete backup restored.
No settings changed, nothing on my end I did to make it work. I just sent a message (MMS) and it worked! I can receive and send to multiple AT&T people AND TMobile accts as well!
UPDATE: VIDEO MMS WORKS!!
At least I can RECEIVE IT - this was shot via SonyEricsson W800i video mode and sent from TMobile to my 3G iPhone.
iPhone is now the ultimate phone! =)
I've already tested text/mms/audio/and now video works 100% as it should with mms. If only the iPhone can send videos...
