This will be the first iPhone cycle that I will not be sticking with AT&T and I am seriously considering purchasing an iPhone outright from Apple.com. However, I need some assistance in deciding which Unlocked version of the phone to get. Is there any advantage besides the different cellular bands the Sim-Free phone receives versus purchasing a T-Mobile/Verizon branded phone via apple.com? or what else should I take into consideration? I should point out I do not have plans for international travel at this time. Any pointers/advice/ect would be most appreciated in helping me make this decision. Thanks!
