Ok so I lost my iphone about a month ago and I was stupid and didnt get insurance on my contract, now If I want a new one I have to pay retail for the iPhone. Not happening. Anyways I have a friend that works at ATT (my carrier) who said he will help me out if I can get an iphone. Another friend of mine has an extra iphone 4s and is willing to sell it to me. The problem is its a Verizon iPhone. I know you can unlock iPhone but I wanted to know how to unlock an iPhone 4s to then switch its carrier, if its possible
