So far, I have been unable to make a design that doesn't involve carrying around a screwdriver, paint can opener, crowbar, iPod opener, etc. Feel free to tell me your ideas—and please do!
UPDATE: Nickels put into the dock port and pushed can open it and pop tops (the tabs found on soda cans) work, although they bend a little.
Step 1: Open it
When you take one half off, don't be afraid to break any wires**. You'll be gutting it all anyway.
*Sorry I don't have many pictures, I wrote this after-the-fact.
**Unless, of course, you need them for the parts you want to salvage...
Step 2: Gut it
• The headphone jack
• The hold switch (you may or may not wish to leave the circuitry for it)
• The click wheel etc.
• Do not leave the dock connector, but DO leave the white plastic surrounding it.
