In what seems to be an endless supply of leaks, OS 188.8.131.522 for the Curve 8520 has popped up this morning. BBLeaks again gave some love with another leaked build today, adding to the Bold 9000 and Curve 8900 leaks from yesterday. I'm starting to like these last two weeks with the insane amount of new OS' that have been coming up. Hit the link below to download.

*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). *
