I too am a T-Mobile user with a 8230 on the West Coast.
As a test I just sent an MMS (text and picture) to a friend on the East Coast with NO issues. It arrived at its destination within seconds.
Where I live I have zero cell service so everything goes over UMA.
Did you set up your TCP (in Options/Advanced)? For me APN = wap.voicestream.com
