I think if Nokia did release all driver source it would benefit far more and be much better liked than keeping everything to themselves especially to the people capable of development leading to better quality support. For example the usb tranciever chip, ok we know it is not wired for otg but hell is not exactly rocket science to put right and look at the HUGE amount of interest in otg which they never will complete without the driver and re-wiring needed. They want to save otg for the successor to the N900, money money money THATS the reason they do this !.
