Just got a new 3G about a month ago...love almost everything about it but I am having a headphone problem: When I plug the stock headphones into my 3G, very casually mind you - like I would for an iPod or cd player, I get no sound. Only when I push with a little more force, as well as sometimes twist the headphone around within the jack, do I get sound...and as soon as I let go with my hand I lose the sound. I'm not sure if I am doing anything wrong or if I just have a piece of faulty equipment. Any ideas? Thanks in advance for your help!
