Replaced aging battery in 3GS

Battery wasn't holding a charge long enough anymore.

Smoothly ;-)

Only tricky part was reinserting the tiny flat ribbon cable (#3) when reattaching the screen. Other than that, a pretty smooth ride.

Take a close up picture of the cables before detaching (especially for the ribbon to get a sense of how far it gets inserted into the connector before you can close the clamp.).
