If you are an owner of the BlackBerry Bold and still running BlackBerry Bold OS 4.6+ there’s a new unofficial OS update available in the form of OS 4.6.0.266 according to CrackBerry.

Some BlackBerry Bold users may have already updated to the leaked version of OS 5.0, but if not then you can always update to this new leaked OS 4.6.0.266 version.

As usual though, 4.6.0.266 is an unofficial OS update and not supported by Research In Motion or your carrier, and thus if you choose to install OS 4.6.0.226 it will be at your own risk.
