Here you can find the Series 60 and UIQ version of the Pocketop IrDA keyboard drivers.They also work with the Palm Wireless Keyboard (Think Outside).The Series 60 version has been developed Chris Faherty and the UIQ version has been developed by Johan Frank AKA bowmanP900 in the forums.Great job guys!
I forgot to mention that the drivers are Open Source and are GPL licensed free software.
