In case trackball issues and return rate statistics have you down about your BlackBerry Tour, a new operating system version has leaked for the device to take your mind off it. You can now download OS 4.7.1.53 and give it a whirl! If you do, be sure to report your findings in the forums!
*OS Disclaimer - This is an unofficial release. 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. *
