We have another announcement of an official OS release for BlackBerry today courtesy as always from the guys over at crackberry, and this time round it is for the BlackBerry Curve 8520 and BlackBerry Curve 8900 smartphones.

The latest version is OS 5.0.0.592 and has been officially released by WIND Hellas for both the Curve 8520 and Curve 8900, so if you are currently running a leaked version which would probably be OS 5.0.0.554 you may like to download and install this official release.

No word on just what OS 5.0.0.592 brings to the BlackBerry Curve 8520 and BlackBerry Curve 8900 so if you do download and install and find anything out of the ordinary please drop us a comment letting us know.

As this is an official release of OS 5.0.0.592 for the BlackBerry Curve 8520 and 8900 there is no need for our usual disclaimer but we d advise you to back up your device beforehand and make sure to remove the vendor.xml file if WIND Hellas is not your carrier.
