Just to let know of the updated .deb file in my prev post. I've not updated the verson number but now it fixes the keyboard opend issues when connected via bt or headphone.
Notes:
1) if the package is installed with the device already connected to bt headset, it won't recognize bt headset. You have to disconnect and reconnect it.
2) Answering call by long pressing the camera button doesn't work sometimes as expected if its done immediately when the connection is established. Plz give at least 2 - 3 sec before doing so.
3) Similar while ending call, if the call is answered by answering machine, you have to give it do its talking for a while before you can actually end the call long pressing the camera button.
4) If you are still having problem with bluetooth headset, plz run the program in xterm with /usr/sbin/PSSwitcher and disconnect and reconnect bt headset and it should print its UDI if registered at all.

thanks
