Have an ipad1 with 4.3.3 I want to update to 5.1.1. I've heard a few different ways to do it, can't find the update bar in the settings and general menu, I've tried I tunes. But there are no updates of any kind for iOS . Help. I'm a rookie so please go step by step. I think this thing has been jail broke so if I need to wipe it and strt over no problem
