Replaced a failed iPhone 3GS Dock Connector

My Problem

The iPhone battery drained out, and it refused to charge again. After testing the charger, I started suspecting the link between the battery and the charger : the Dock Connector

My Fix

I swapped the dock connector. Took a few hours, working slowly. So many different screws...

My Advice

Don't try and use an adhesive to remove the screen, it leaves marks. Use a a suction cup.
