[69s fine 68s great]

Ok i have been a verizon and sprint user for quite some time now and decided to go to T-mobile. I have the tp2 but was wondering am i able to use the roms from cdma or do i have to stick with the gsm roms. If im correct t-mobile runs on gsm. Please forgive me if all this that i am asking is irrelevant. i have flashed roms on my moguls, touch pro, and omnia before, but i just need to make sure i am doing it right since i am running t-mobile.

Also without flame, can someone direct me to flashing the newest radio(steps on how-to and best radio version) and giving a recommendation on a rom that has most of the bells and whistles... (steps on hot-to and best rom)
