I went to the apple store today to have them look at my iphone because my home button was not always working. Of course it was working fine when I went to apple but they replaced it with a new phone with no problems. I do have a question I had 4.3.4 on my other phone this is 4.3.3 I am happy about that because I can jailbreak again. So can I go to itunes and set it up as new or as back up if I do back up will it install 4.3.4 on there and if I do as new will it keep 4.3.3 and will all my contacts still go on my phone thanks in advance for the help.
