i made the mistake of taking my n770 to work in order to listen to music. long story short, the headphone jack was under pressure in my pocket. now its broken, the ?pins? in there are deformed. when i just push the plug in, i only have mono sound. when i tip the jack a little bit to the side, its stereo again. i dont have tools to open the n770, what could i do?

this was such a downer for me that i left the n770 for a few weeks untouched, i was even planning on returning it. but now i have "restored" it, installed new tools etc and the only thing thats still annoying is that i cant use the headphone plug as it is intended.

any ideas?
