Last week, there was a leaked unofficial Blackberry OS 18.104.22.1688 for Blackberry Curve 3G 9300. I am so curios to try the Blackberry OS version 6.0.x.x since my Curve 9300 still run version 22.214.171.1244. Today I downloaded the new software and upgrade my Blackberry Curve 3G 9300 from version 126.96.36.1994 to 188.8.131.528. The upgrade process took around 30 minutes. It run perfectly in my device without any problems. Cool and amazing OS.
