iPhoneHeat How to restore iPhone app data from backup | iPhone Atlas The iTunes App Store has been around for eight months and now lists more than 25,000 apps. If you're like me, you've probably purchased a dozen or more of these apps and hopefully, you're backing up your computer regularly to protect your purchases.
