The build reportedly being pushed out is IMM76I and is there to fix problems users were experiencing regarding loss of signal. There are no other changes to the OS version, radios or kernel so it you are having signal loss issues you might want to update. If the refresh is not yet available for you then you might want to manually grab it from the source below if you are rooted with stock recovery). Users with no root will have to wait for the OTA and those using ClockworkMod will need to wait for a compatible version.
