Boom! Your done. It took me 32 minutes to figure this out with out damaging the dock.

I can do it in 3 minutes now that I've mastered the process.

If you don't replace the white top cover of the dock when reassembling, you will have a universal dock, that can also be used with an iPhone 3G/3GS.

It will also work with any iPod with a 30 pin connector.
