On latest stable. Everything runs smoothly on my x9006, except 2 things:
1. Most annoying bug/unclear settings/fckps/fubar/annoyance:
Hanging up! The phone just ignores pressing the big red button.. It's ok when you talk to someone, because it will end soon after they hang up. But answering machines... guess they end out of tape, if you don't manage to kill the call.
It did happens for me 3 out of 5 calls, until I added "hang up with powerbutton"....
-It's dead Jim..
