We just checked the availability of any firmware update on our 808 PureView and above message welcomed us. So, yes it seems the Belle FP2 update for 603, 700, 701 and 808 PureView is now rolling out OTA and the updated Firmware version 113.010.1506 seems to be the same for which we posted the probable changelog before.
So, what are you waiting for. Do *#0000# on your device and check for the update :).
