I did with my first G1, after dropping it one morning. The USB connection broke internally. I worked with Steve Kondik on it for awhile, hoping it was something simple, to no avail. In the end, it just required a bit of solder.
Empirical evidence can never establish mathematical existence - nor can the mathematician's demand for existence be dismissed by the physicist as useless rigor. Only a mathematical existence proof can ensure that the mathematical description of a physical phenomenon is meaningful.
