It hasn't been too long since the BlackBerry Pearl 3G had an OS update, and today it has another. OS 188.8.131.521 has popped up for this device, so if you're rockin' a Pearl and want something to do today, go ahead and give it a go. Just like other leaked OS', this one is not official in any way so be sure to back up all your data if you decide to load it up. Of course, be sure to share all your findings in the comments and in the CrackBerry forums.
*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). *
