I have a blackberry storm and it's served me well. Everything on it works perfectly except the audio jack is starting to die. Whenever I plug in my earphones/headphones it only plays music on the left side. It's not the headphones and I don't have any lint in there. If I play with it a little bit, I can sometimes revive the music on the right side for a while, but if I nudge it the wrong way the music dies and I'm left with music on one side only. What part do I need to replace? What's wrong with it? Thanks.
