SO... for domestic US users, the choice would only be ATT (gsm) or T-Mobile
(gsm)
while the global (gsm) market would offer more choices...

Just curious, as some of the financial chatter about AT&T and Apple
have indicated that Apple would loose a lot of revenue if these phones
appear on other carriers - and then Apple would not receive their ATT shared
revenue.
ie - the "sold" numbers from Apple vs the "activated" numbers from ATT
indicate a disconnect and therefore the delta is the "unlocked" world.
