I ordered an iPhone 4 for my mom. I told her to have one of the (iPhone 3G/S owning) relatives to back up her iPhone 3G. Just back it up. INSTEAD of simply backing it up, our relative did something, I don't know what, but called me to ask why nothing restored but 4 songs. All of her data is gone! I don't know what was done or why. I am in a different state, and they did the opposite of what I instructed. Is there ANY way to restore backed up data IF it was indeed backed up through iTunes? They're using a Windows computer. Is it somewhere in a system directory? Can Apple tech support help? I'm livid right now because I assured my mom that all would be fine if she did what I told her to do.
