How to Restore Cracked iPhone Screens

By Marshal M. Rosenthal

The iPhone 3G’s portability has led to many not realizing just how fragile the glass screen on the front is. Restoring an iPhone 3G which has a cracked screen requires removing the screen and insetting a replacement screen. The procedure for opening the iPhone 3G to replace the screen is straightforward once you have purchased a replacement screen from an iPhone 3G parts supply store. No electronic expertise is needed to restore the iPhone 3G to full functionality, although doing it yourself will void the Apple warranty.
