I just received a replacement nexus one and it came with original 2.1 firmware. It does not detect that the ere27 firmware is available and so will not update OTA. Does anyone know how to get this thing to update? I haven't had problems before and this is my third ne us one. The previous 2 saw the update almost instantaneously while I've had this one for 2 days now and nothing. Any help would be appreciated.
