My first Palm Pre lasted for 2 months, I got a refurbished replacement because it was developing a crack across the screen. After a week the refurbish pre earpiece crap out. I then got another refurbish Pre and it only lasted for 2 weeks with the same earpiece problem. If I press on the back of the earpiece, the voice fades in and out. It looks like the solder probably worn out because of the phone heat. Could a patch or the 800 kernal cause this? Please help..
