Looks like RIM is still showing some love for the older Curve series.
The BlackBerry Curve 8520 Official OS5.0.0.1075 has been released via Vodacom South Africa.
It's been a long time since we have seen an official release for this device so if you have one get out that USB cord and give your device a fresh new OS. As always please be sure to let us know your findings/fixes.

The Software Platform and Applications version numbers can be found under Options-About screen on the handheld.
