iPhone Parts List Help!

Every iPhone produced so far has 3 pieces of glass that form the iPhone Front Screen. 1 the front glass that you touch with your finger. 2 the digitizer that responds to your finger touch. 3 the LCD display that shows the screen image. The iPhone 3G and 3GS normally have the front glass fused with the digitizer at the factory. This is usually purchased as the front screen with digitizer (with adhesive strips) as one piece and has Flex Cable #2 connected to the digitizer. This is what usually cracks when the iPhone is dropped. If the iPhone has image problems then the replacement to buy is the LCD display and it has Flex Cable #1 connected to it. The LCD display can be purchaced with or without its metal backplate. The LCD display has adhesive that holds it to the metal backplate, both of these are attached to the midframe with screws.

If you decide to replace the entire Front assembly, you get Front Screen, Digitizer, LCD Display, Home Button, Earpiece Assembly, Midframe, this is everything. You can also buy the Front assembly without the LCD Display (this is what many buy). YouTube has videos of the repair and installation process.
