I have a really weird issue with this phone. I love it a lot, so far, but there's quite a significant problem when listening to music. Occasionally, I'll hear a pop (sometimes it doesn't even do that) and then it completely crashes. Like, the screen goes blank and goes to a red "M", as if it was rebooting. I've tried it with multiple headphones (as I thought one was just old and somehow shocking the phone into an emergency shut-down) and multiple music players (jukefox, poweramp, and now winamp), and it just keeps happening. No rhyme or reason, sometimes it happens multiple times in a row. This phone has been great to me thus far, but I'm beginning to think I got a defective phone. Unless anyone else has been having this issue?
