Here is a little bit of a treat for all you new 8520 Curve owners out there, a fresh new OS for ya's to load up. Having just gotten my 8520 today it was nice to see that the OS leaks were not gonna stop based on device. Best part about this leak--their is a full change log included for you all to have a peek at, enjoy folks!
*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. *
