Just found out that an update has been pushed to my phone to update my Nexus S I9020A to v4.0.4 which is the same version number but different build IMM76M instead of 76D. Kernel is the same, and the baseband is the same too. Can't find anything on the net about it though so don't know if I'm the first to see it or what? It may be a minor fix for the silent ringer when using bluetooth? Anyone else get the update on their I9020A GSM model?
