I am sure this is a total n00b question, but I've never done this before. My iPad2 is acting up on me lately, especially the Appstore gives me weird messages. Also it fells like sometimes it does not respond as quickly as it used to be on keystrokes. I thought I might try to factory-reset it and see if that helps. But what exactly will I lose by doing so? I will backup everything in iTunes first, but what about data stored in Apps (like Evernote, Next!, Notes) and progress in games (like Tiny Tower most of all, but others as well) ?? I am not using any iOS cloud services, so everything not saved in iTunes will probably be lost? Thanks for any help!
