A:AnswerAll iPhones since 2012 come unlocked TMK. Personally, i buy Unlocked directly from Apple so i get minimal carrier bloatware on my phone, and to ensure i can activate with any carrier i want.
A:AnswerApple Store sells an Unlocked version at no extra cost, meaning you can activate it with any carrier. It's where i go to buy iPhones unless i can get it with BB if it's in-stock.
