    My iPhone won't update to iOS 5.1
    I've had it for almost a year and can't remember ever updating it, I didn't know you had to
    But now it won't install any new apps and stuff because I have iOS 4.2 something
    When I plug it into my computer it asks me if I want to update to 5.1 and I click yes.. and it starts to back up and restore and then it comes up with this error message and just stops..
    Is there anything I can do to make it update?
