4.0.4 is out already is it not? There are Roms for the GNex available. Edit: It seems the 4.0.4 roms are based on the LTE release with a GMS compatibility layer so may not be much use to us. In ICS I can make and receive calls. Obviously with media server crashing the person on the other end can't hear me, but if you have a newer build I will quite happily test it for you. My N900 is kinda redundant at the moment as it's no longer my main device so I can test anything and everything without fear of killing my device
