Everything works for me. Have not tested wifi, Bluetooth and usb tethering is good.
Only problem i have is few random restarts. Maybe twice a day. But the battery life, low ram usage and smooth performance is so excellent, it doesn't bother me.
All and all, very stable and functional for nightlies.
Back and menu button lights up every time you touch the screen, only supposed to light up when you touch then.
In the radio app, volume buttons doesn't work if phone sleeps.
Using 041113 cm nightly, allot may have changed since
