Audio jack bearly working.

I just want to share something that happened to me: i had an ipod touch 2nd gen, the audio jack was bearly working, sometimes only working the right or left side, sometimes skipping the songs or just low level sound. for a little "mistake" i discover that touching one of the golden parts inside the jack with any other metal object fixed the problem. i guess grounding it (audio jack) fix this problem. Hope this will helpful for everybody, i wish this could help not only the itouch but many other idevices!!!
