Apple gave a wrong iphone 5
Ok so I had a iphone 5 64gb which was unlocked and I was using it on tmobile by then it started freezing at randomly. When I would touch the screen it would not work so Snice I had warrenty I took it to apple and they swapped it out for a new one and I was pretty happy until i went home and realized it wasn't unlocked no more. I went home a checked the imei on this site and realized its sprint iphone 5 and now I'm stuck with this Snice I don't have the receipt neither do I have a carrier that supports this phone and apples asking for a proff. This is the worst thing every because now I have no phone and this phone is useless.
What can I do and have you had anything like this happen to you before if so please share.
iPhone 5, iOS 6.0.1
