I've got one!
Damn thing refuses to hang up at times unless I switch the thing off, and other times it refuses to dial. It also hates to latch on to a new stronger signal while you're moving unless you (again) switch it off and back on.
Now whether that's Window's fault or LG's I couldn't tell you. The "send feedback" function is also disabled. I guess they don't want people telling them to "shove it".
