Headphones not working after ics upgrade. Upgraded to ics about 3 weeks ago - like it a lot, but ... just tried my headphones on to listen to some music and discovered headphones not working. Phone speakers work fine and headphone jack has no effect on the phone speaker when it's plugged in. Verizon wanted to try a factory reset but I thought I'd ask the real experts first if there is any other thing to look at.
