Book this repair if your front glass is cracked, smashed or unresponsive. If you can see your icons when your phone is on you only need your digitiser replaced. If you fancy a white screen instead have a look at our iPhone 3GS white screen conversion.
Is your back case a bit scratched up too? How about a full refurbishment of your iPhone?
If you cannot see your icons you will need your LCD replaced too. Click LCD repair for this.
