Wow, it’s been a long time since we’ve seen any leaked OS’s for any devices. We’re not exactly on top of them as we’re here primarily for other reasons and we’re more interested in BlackBerry 6 than every loose end RIM has yet to tie up with all the different OS versions for each device. Either way, this is the highest OS version number we’ve seen yet for any of these three devices! There is no changelog associated with this leak, but I’m sure it’s only minor performance upgrades here and there. If you install it and notice any huge differences, let us know in the comments or our forums.

If you’re interested in downloading any of them to your device click the following links:
