couldn't you have just taken off the 2 screws at the bottom of the phone and popped off the back plate and cleaned it yourself.
its incredibility easy to do and their are several videos detailing how-to.
this also applies to Alexjones.
Sure.. but I didnt feel like opening up the phone and messing with it no matter how easy it was. The hold button was also very loose, and the antenna was very sensitive. So it was one of a few problems that were all resolved in the replacement unit.
