I just bought an international 525 on Amazon, unlocked. Completely unbranded in every way. I popped my AT&T SIM into it and could make all the calls I wanted. Unfortunately, it only got Edge data because the international 525 doesn't support AT&T's 3G/4G/LTE bands, so I returned it. But the bottom line is that if you buy a new, international, unlocked Lumia from Amazon, that's what you're getting.

That makes no sense. Unless you're talking about the developer unlock (which is done through the WP SDK, not by a carrier) a carrier unlock IS a SIM unlock. So if TMo unlocks the phone, they're SIM-unlocking it so you could use it on AT&T or another GSM carrier.
