Fixing your iPhone is quick and easy! Find replacement parts for your iPhone at
The first thing to know to is what part you need to replace. On the original iPhone display, the glass, touchscreen digitizer, and LCD display were inseparably glued together. Fortunately, Apple changed their design and the iPhone 3G and 3GS front panel glass is not glued to the LCD behind it. This is great news, because most of the time when you break the glass the LCD itself is fine.
If you want to save a little time, you can buy a complete front panel assembly that includes the LCD and the front panel glass.
Make sure you get the right part for your phone—the iPhone 3G and 3GS require different parts.
