Hi guys and girls, I've had a strange issue develop with my iPhone recently that's bugging me. Here's what's happening: When my iPhone plays music through either it's headphone jack or the pin connector (i.e through a dock or FM transmitter), sound is played on both sides (left headphone and right headphones), but it is only playing the right channel, and not the left. So when i play a song by The Beatles for example, music will play through both the left and right speakers, but I will only get half the song (as you may know The Beatles split a lot of their tracks into left and right). What further interests me is that if I switch the iPhone settings to play in Mono (in accessibility settings), both channels will play in the mono setting, so I can hear both sides. If I play a song through the iPhone's speaker, I can hear both sides (but I'm guessing that's because it's playing in Mono, as it's just one speaker) and I can slide the L/R balance to hear both sides of the track by themselves. This doesn't particularly frustrate me, as it's not a big issue, but I'm an engineer, and that I couldn't fix it myself was a little annoying! Ahaha It's and iPhone 4 on the new iOS5. I'm guessing a iPhone restore would be my best option? Thanks for any comments/help!
