Gingerbread for Nexus One..and wait....
Well, if you were like me and expecting to see it released for, or around Christmas\new year it seems we have a little while to wait yet according to this report.
Nexus One: Android 2.3 Gingerbread – Release Date ETA Update : Product Reviews Net
So whilst we can possibly expect it in January it will most likely be Feb (or March) before we see it. Perhaps they are ironing out any bugs reported from the Nexus S first, or more like Google showing that it's once golden child is now being shunned?
