This guide demonstrates how to replace the the cell phone faceplate.
Find the small notch on the side of the phone. The notch is located by the "fast-forward" button and the "lock" switch.
Insert your plastic opening tool into the notch.
Pry off the faceplate by gently sliding the plastic opening tool around the phone while still keeping the tool under the edge of the phone.
When enough of the faceplate has been lifted it can be easily removed.
