same prob
I'm having the same problem. got my x replaced and the new one didn't do it for a month, now it's started again, mostly happens with headphones, but can happen with car. mostly when i'm moving around, which make me think that a little slack in the jack is causing it to send a signal similar to headset buttons to start playing music or something to that effect. moto needs to update froyo to solve the problem, but everyone needs to contact them telling them that it's a widespread problem, give details, and that sending new phones one after another isn't going to solve the problem. ha, it's really annoying me. hope someone finds a solution wether or not it's moto, i don't care
