iPhone remote (share what works)

[FAsnakes]

I was rifling through some old boxes in the shed and found this old remote from a CD player. The remote connects to a audio device and has a bunch of controls (volume, seek, skip, pause and play) I connected it to the iPhone and the only thing that worked is the volume and the ESP button)
Check and see if you have anything lying around and report back what works. The remote would be awesome for the gym and general ipod use. (that way you don’t have to remove the iPhone from it’s pouch to rewind, fast forward or seek).
Here’s a pic of the remote I had.
