I modified mine because I wanted to make a clean car mount for my new Galaxy Nexus http://goo.gl/CkJMn
iFixit has a tear down that does not include full disassembly instructions, so I've included more comprehensive step-by-steps here.

- Right Angle MicroUSB Cable ~ $5
Note: these come in 'left' and 'rignt' handed configurations. Both work.
- X-Acto Knife (or similar)
