Didnt knew where to put this for topic for discussion as there was no hardware section.
So the mods, if u find a better section shift it there.
Coming back to the topic.
Is it possible to replace the joystick of K800i ( and for the matter of fact, any SE phone... you know they are difficult to operate after some time and become faulty easily ) with the joypad of W550i ( or any such joypad ) ?
Do some research on it people ...
below is the best shot of joystick and the w550i joypad available on the net.
