Hi - could someone please suggest instructions for this task: I need to upload one track onto a variety of different iPods belonging to different people, and those iPods need to be empty apart from my track. When each user has finished with my track, we need to wipe my track from their device and ultimately replace all their music library they had before we started. They will be bringing their iPods to me for the track they need, and so I'm telling them to back up their music library beforehand so they can restore it after we're done. Where can I find instructions that I can send the users for backing up their libraries so they can restore them afterwards with the minimum amount of fuss? For loading my content onto their devices, I will be using iTunes and syncing their device to a library on my own laptop that just has the one track. This won't create any special problems for them to restore their libraries afterwards, will it? Thank you for any assistance!
