Looks like this one flew under the radar last week, but Bharti Airtel has officially released OS 188.8.131.521 for the BlackBerry Bold 9780. This is the latest and greatest so if you're rocking a Bold 9780 then have at it. Reports look to be good thus far. If you do install be sure to swing by the forums and let us know how it is. As always, use caution when updating your device.
