What does restore from backup do and backup and restore as new device mean?
There is a issue on my iPod 4g 16gb and Apple said backing up and restore as a new device will help fix the problem. I am not getting a new device or anything, I'm using this iPod. I know how to do a backup, but what does restore from back up mean? Does it delete anything? Will apps be included in the backup? Also, I don't know what backup and restore as a new device means. Sorry for all the questions but I've got apps, photos, messages, and all that are important to me and I want to make sure restoring or something doesn't delete stuff. I will be using iTunes by the way, no iCloud.
