Just recently noticed my Hero is no longer recognizing my headphones. I've tried about four or five different pairs of phones to make sure the ones I had weren't bad, so that's not the problem. Anyone else ever encountered this problem? Also, I just got my phone around New Year's, so I'm obviously still under warranty. I went ahead and used the restore feature so my phone is back to stock instead of being rooted in an attempt to appear as if I haven't voided my warranty. Think this will work?
