Hey guys, I got an iPhone 3G yesterday (Saturday) and it seems like the left earbud speaker on the included set of headphones does not work. Has anyone else had this problem? I know it's a problem with the headphones, and not the iPhone itself because I've tried two other headphones (from an ipod) and they play in stereo. Thanks for any help/suggestions you can offer. I've got an appointment at the Genius Bar tomorrow afternoon... hopefully they'll just be able to give me working set!
