T610 - 900/1800/1900mhz
T616 - 850/1800/1900mhz plus some att/cingular crap on it.
Impossible to change from one to the other. Hardware based different chips for bands.

yeah but if you turn your t616 into a t610 with a fw update won't it work with t-mobile?

I read somewhere that Cingular will give you the unlock codes after your contract is up. Once ATT becomes Cingular, they might give you the codes.
Make sure you check to make sure your phone is locked (right, *, left, left, *, left, *,1,2.) I have a Cingular T616 that I bought from Best Buy and all 4 padlocks are open. I would have figured it would be locked but it isn't (I have not tested this w/ another companies SIM.)

As long as your T616 is unlocked, it will run with T-Mobile. The 900 came isn't required in the US.
