this has happened to me about 4 times in the year i have had the phone. Soft reset, hard reset, plugging and unplugging...nothing seemed to have an effect. the last two times it has happened i found that just the right sequence of plugging the headphones back in, soft resetting with them in, then removing them and soft resetting again has done the trick...mighta just been a fluke since hardware or software, this bug seems to have a mind of its own and goes away when it wants to.

but give it a shot...
