Tour owners are on a roll now with leaked OS'. This is the second one in just a few short days. Here we have OS 22.214.171.1242 for you all to check out. Since I'm not a tour user, I really can't speak to how well it works but I'm sure you'll find some information in the CrackBerry forums from users who have loaded it already. Give it a shot, just be sure to back up your data first folks.
*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. *BBLeaks
