Hey everyone, I noticed that Targets in my area have a plethora of AT&T units available of the iPhone 6 plus, and I was wondering if I am a T-Mobile customer can I buy one and use it? Or if I call AT&T will they just outright unlock it? I haven't had AT&T service in about 5 years. I hear that units you buy at the Apple store tend to be unlocked no matter what carrier you get if you pay in full and I was wondering if that also extends to Targets or other retail locations. I am cool with giving them a call to unlock it (AT&T) but I know that T-Mobile will only do it for phones that have been active on their network at least 30 days or 60 days or something, and if AT&T does the same then obviously its better to just wait for a T-Mobile unit to become available. Any experiences/advice would be appreciated. (Alternatively, would I be able to get a friend who has an AT&T account to unlock for me without giving them the unit?) Thanks!
