I think your right. The Touch HD will work on the 850 mHz band. "T-Mobile offers GSM service in both the 850 and 1900 MHz frequency bands. T-Mobile offers EDGE data service over most of their network, plus WCDMA 3G voice and data in select metro areas, using the 1700 MHz band. "

Looks like there edge data network is on the 850 band. Sure will be slower than your used to on Sprint though. I know my brother can hardly stream video using AT&T's edge, but if you don't do that then just surfing the internet may be tolerable.

Go get that Beast activated, I'm curious!!
