BlackBerry Tour owners have kind of been left in the dark when it comes to OS leaks. But, today ends that drought. OS 188.8.131.521 has just sprung up for all you Tour owners who are looking for a new OS. We don't have to tell you this but we will anyways, it's a leaked OS so be sure to back up your data before loading it up. Also, be sure to drop some comments here or in the CrackBerry forums about what, if anything is new within the OS itself so that others may know.
*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). *
