Nokia got a great little headphone/remote AD54
nokia.co.uk/find-products/accessories/all-accessories/headsets-accessories/wired-headsets/hs-45-ad-54
(mine came with a N95 from back the symbian days) which is perfect for turning the phone into a great hands free music player. the plug is the same 3,5mm with 4 contacts as the one from palm.
Is there a way to make drivers so we can use it with the pre?
I suppose we could use xev to get the key codes from pressing the keys (as with mapping extra keyboard keys in linux).
By the way I think that the headphone jack could turn out to be one great extension port if only we could get to the documentation.
So how about a little hardware hacking?
