Ok i see tons of topics about the unlocked iPhones, sim-free iPhones. T-Mobile version will come unlock because you are paying with full price. But if you have suspicious i'll come to Turkey on September 28. I'll bring my phone with me and won't open the phone until i get off the plane and put my regular Sim card beside of the T-Mobile sim card. And i'll send message here whether my sim card works on the T-Mobile version.
