I am going to purchase a 3G iPhone from a friend. It's jailbroken and unlocked. I know because I've already put my T-Mobile card in and it works fine. I currently have a 2G model that I will sell. When I get the 3G and connect to my iTunes at home, will I be able install all my contacts, apps etc, without having to re-jailbreak and unlock, or will I need to go through the process again
thanks in advance
