How much would a brand new factory unlocked iPhone 4S cost me?
I'd also like to know: if I purchase a factory unlocked iPhone 4S and utilize T-Mobile's HSPA+ network, would I be able to access other carrier's networks in the future with that factory unlocked device?
For example, I purchase a factory unlocked iPhone 4S, use it for a year with T-Mobile, but then switch carriers (ATT, VZ, SPRNT) would that device be compatible with the other carrier's networks as well? Or would I only be able to tap into their networks with their specific phones they offer via contract?
