Given these criteria, which model numbers should I be considering?
I've heard that the t-mobile one has the unlockable bootloader. Does it support all the bands to use AT&T towers?
I've seen more than one model number for international units. Are all the bootloaders unlockable? What's the deal with the region-locking? Will some of them work better for me than the others?
There is no unlocking of bootloaders. It's either unlocked, or locked from the factory.
To answer your question, get the G900T (the tmobile version). You can get this at costco, best buy, target, .... and of course a tmobile store itself. It supports all of AT&T's bands and more.
