*10 POINTS BEST ANSWER*
Well I already started the update to iOS 7, and have a quick question. If I update my iPad to iOS 7, will my data be deleted? I use my iPad at school and we use it to take notes and all, so if everything gets deleted then I have to recopy all the notes and all. I can't back it up since I have been getting an error lately when I try backing it up, plus I have already started the download. PLEASE ANSWER FAST! Thanks!

Sadly, it isn't compatible with the iPod 4G.
