OS for the BlackBerry Tour has been leaked.  My guess is that, with the increasing frequency that we are seeing leaked 5.0 releases of the BlackBerry OS, it won’t be long before RIM and the various carriers get around to officially releasing it.

As always, leaked OS updates are unsupported, so, if you plan to install, make sure that you know what you are doing and that you get a good backup of your Tour before you start.
