My sleep wake button is broken so apple said I could go to my apple store to get it replaced. My current ip4 is JB should I un jailbreak before I go replace it ? And when I get it replaced can I JB the new iPhone? Or does it come with 4.2.1 in which case I will have to wait for unthedered JB. on a side note having the button broken isn't hampering my daily use of the phone so should I wait Til 4.2.1 is jb then get it? Thanks everyone!
