iPhone 6 contract-free
Does anybody know if the t-Mobile contract-free of iPhone 6 is the same thing of an unlocked iPhone? Cause I'm from Brazil and I wanna pre-order an iPhone 6 for me, but I'm not sure if it will work here in Brazil, cause we don't have t-Mobile here and I don't know if the contract-free will only work with the t-Moblie SIM card or if it support all carriers.
iPhone 5s, iOS 7.1.2
