When I listen to podcasts on my Pre using headphones the phone does a complete reset. This happens after ten minutes or twenty minutes...there is no pattern. Even after the reset it might reset a second time several minutes after the reset. I thought it might be the headphones so I used a second set and it did it again. This happened before the update to 1.3.1 and continued after. I walk 30 minutes each day and I can't remember the last time I got all the way through a walk before a reset. Any thoughts?
