Hello. First of all I`m sorry if any bother to ask dumb questions. 1. Is it better to have the latest updated software on the iphone? 2. I have a 1.1.1 iphone, bought it already unlocked. Recently the iphone cannot sync via itunes. There was a similar thread about this and a moderator said to restore 1.1.1 back again. Would that involve re-unlocking the iphone? 3. Can I break my iphone if I unlock it bad / try to update and so on? Thanks and have a happy new year!
