Last week we saw the official release of OS 126.96.36.1996 for the BlackBerry Bold 9700, now we are hearing that an unofficial version of OS 188.8.131.521 for the BlackBerry Bold 9000 has hit the Internet.
As with all of these unofficial releases, details are scarce, no-doubt there will be the usual bug fixed and interface tweaks, personally I would wait until the official release before installing just in-case this leak is unstable.
If you understand the risks you can download the OS here, however I must advise you to backup all data beforehand just in case theres a mishap.
