2101,
Except for once bricking my phone (I think because I killed bme's configuration, since nokia claimed all they did was a reflash and it started working, for me it wouldn't respond to any usb cable connection, from PC or power),
everything is working solid, keys are a little scratched but I am using a game gripper, and I do notice that the slider is, barely, touching the keys. No USB problems even though it fell connected to the cable a couple of times.
