About pinball: I do not know but pushing hard and frequently may speed it up. I never played with N900s and was very cautious. But this is due to a design mistake or bad production (like the USB port or other failures like the N95 slider rails, N97 GPS antenna and and and) as so many devices were affected. I did never believe in that paper, spring, bakening voodo but just enabled another device. The same you should do but I understand that it is a real hard task to choose one of the 58s.
