I have a new iPhone 4 32GB. I love it!...BUT, I seem to be having an issue with my headphone jack. When I connect my headphones to the iphone's jack there is little to no resistance when the plug pushes into the jack. After the plug is firmly and properly in place, I can only here faint sound coming through my headphones even though the volume is turned all the way up. If I make micro adjustments to the plug in the jack the sound finally kicks in and I can hear the way I'm supposed to. I don't think I should have to do this everytime?! Is this a known issue?...dare I ask. I have tried multiple iPhone headphones with this iPhone 4 and have the same issue with every one of them. So, it ain't the headphones. And yes, I'm connecting the headphone plug properly and completely into the jack on my iPhone 4, with volume turned all the way up. Never had this issue with my 3G. Still within the 30 days but I hope I don't have to return it as my local store is sold out of new iPhone 4's... Oy vey. Thanks!
