Lately we have been seeing numerous OS leaks for BlackBerry smartphones, only last week we had a leak for the Blackberry Curve 8900 and BlackBerry Bold 9000 in the for of OS 5.0.0.348, and now according to an article over on Crackberry, the BlackBerry Curve 8520 sees some leaks OS goodness.

No doubt over time official OS 5.0 updates will hit all BlackBerry smartphones, but until they do these leaked OS sure come in handy for the BlackBerry faithful.

A quick spec reminder, the BlackBerry Curve 8520 sports a 2.46 inch display, full QWERTY keyboard, optical trackpad, WiFi, 2 megapixel camera, Bluetooth 2.0 with A2DP, 3.5mm jack and microSD expansion.

As this OS 5.0.0.348 is not an official operating system release, the usual disclaimer applies, and should you choose to install you do so at your own risk, otherwise you can simply wait for an official release for your BlackBerry.
