Today we repaired this broken iPhone 4. The screen and the touch panel are working but the front glass is broken so it is difficult to use the phone and it looks very bad.
We replaced the front panel with a new panel and now you can see on the picture that the iPhone is like new. Those bubbles on the repaired iPhone are from the protection plastic that come with the new phone.
