Hi,
I have a similar problem, not the Headphone Jack but the Volume Rocker Switch is buggered. The headphone Jack does have a partially broken plastic surround but probably not bad enough to need to worry about replacing it.
But after the most recent drop my Nokia N8 volume switch only works in one direction... Down. So I can't turn the volume Up... unless I use the touchscreen volume slider (which isn't always available). So oldturkey03 I'm hoping your instruction manual will tell me how to replace one of these things too.
So having said all that, oldturkey03, could you please share the rights of your repair guide with me as well, to allow me download.
Regards,
