Been getting that OS upgrade itch as of late? If you have a BlackBerry Bold 9900 then you can go ahead and update to the latest official OS if you think it might help. WIND Mobile has gone ahead and released OS 22.214.171.1244 for the BlackBerry Bold 9900. It's not a leak or anything but official OS' are often times just as good. If WIND Mobile isn't your carrier -- make sure you delete that vendor.xml file first before loading and always back up prior.
