Have you changed the APN settings to T-Mobile:

1st things 1st though:Are you SIM Unlocked?

If so,did you have the phone data/WI-FI working on T-Mobile before you flashed the SkyDragon ROM?

Thanks for fast response. APN set, SIM unlocked
Everthing worked as it should except texting photos, ATT/ tmobile issues

Flashing an AT&T RUU may be your best bet & then starting over.

I'm not sure if you have to go back to S-On &/or relock before running this.

There's a lot of resources for your phone @ XDA-Developers:

Before diving-in,I'd ask around regarding flashing RUU's/updating/etc.... as you're probably painfully aware that AT&T has a propensity for locking things down on later O/S,etc...... don't want ya to get stuck w/a stock unrootable device,no fun in that.

With any luck,you'll be able to flash some radios/etc... to get back up & running.
