Ahh, the BlackBerry Tour. We heard at WES that the Tour branding was no more, so it's great to see that new OS' are still being pushed out. Be it official or leaked, I'm sure Tour owners will enjoy it either way. As with all leaked OS, use caution when loading up. Be sure to back up your data folks. This one remains untested by us, so be sure to share your thoughts in the forums and comments if you install it.
*OS Disclaimer - Please Read: Keep in mind this is NOT an official release and as such is not supported by RIM or your Carrier. If you choose to install, do so at your own risk and only if you're comfortable in the process of upgrading and downgrading your device software. It is quite normal during operating system development for certain features to be crippled or disabled while others are tested, and these beta builds often reflect that. They are not always better. Depending on your BlackBerry comfort level, it may be best for you to wait for community feedback on a build before deciding to download and install for yourself or simply wait for the next official release. If you require support, you will find it in our CrackBerry forums via our extremely knowledgeable community base - do not contact your carrier or RIM for Beta OS technical support (their first course of action will be to advise you to downgrade to a supported OS). Follow the links below for more information and instructions. *
