My iPad is apparently running an outdated iOS. I had tried to do something in the App Store I think (bad memory) and it said I needed iOS 5.0 or higher. This will be my first attempt at upgrading. I'm a Windows person and am just uncomfortably unfamiliar with Apple. I don't have a backup of my iPad, which weighs heavily on my mind. (I have the instructions, just haven't had the time*) Can I upgrade simply and, if so, how so? Through the App Store? If I'm a few or more upgrades behind, can I just upgrade to the latest connection or do I need to go through each upgrade? I am on my PC and can't check version right now but my iPad is iPad 2. * I bought a cable to connect my iPad to my laptop. One end is the PC USB flat connection, the other is a tiny odd-shaped thingie. Label says 1M USB A to MINI-B 2.0 CBL. Do I have the right cable to merge/marry them?
