I have an iPhone 5s 16gb for sprint which is practically new. My friend had a couple of upgrades on his family plan and ended up giving me one for free as a gift. Its been a while now and no unlock solutions have been announced. I am on at&t and someone has offered to trade me their used samsung galaxy s4 (at&t version) for my iphone. Sprint is coming out with its new unlocking policy which will take effect in 2015, allowing them to unlock phones for domestic use but I'm not sure if it applies to phones from this year.
