I was wondering.... If I have an iPod that is updated to ios 4.2 and haven't updated it to 4.3 yet, and I want to update it on a different computer (because my other one got destroyed), can I do it? NONE of the stuff that is on my iPod is on the other computer, so if I sync and transfer all the files, it will most likely delete all of the stuff on my iPod. Can I update my iPod without anything being deleted?
