Hi! My name is Susy and I live in Italy. I have an Iphone 4 pre-used (from CANADA - Roger), gift of my cousin. With a gevey sim, I used this until 2 weeks ago. One morning, my boyfriend upgrade this at IOS 5 and now it's lock. I'm not a developper and I don't understand nothing about it, but I can't think that it will be lock forever. Please help me!
