Holy Geebus. Talk about leaky leaky. After OS 126.96.36.199 showed up in the forums for the BlackBerry Storm 9530 late last night, our pal TimBuk2 sent in some BlackBerry OS download links for the Tour, Bold and Curve 8900. For the Tour, version 188.8.131.52 is pretty old now and kinda buggy, but OS 184.108.40.206 is hot off the press for the Bold and 8900 and makes some jumps forward with OS 5.0 including the appearance of threaded SMS (as pictured above)!! Finally - a native threaded SMS client on BlackBerry! Tabbed browsing is gone (for now at least) in .190 but there's some other cool features too, like theme previews upon downloading and a few other tweaks (just installed an am playing with it now)! Be sure to visit the Storm OS forum and Beta OS forum (for all other devices) for the details on all of these versions.
*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. *
