The last time I checked, the most recent official software for the BlackBerry Curve 8900 was OS 18.104.22.1681. Optus Mobile are now listing OS 22.214.171.1241 for the Curve 8900 so it might be worth checking out. Let us know if you see any major or minor improvements.
Download OS 126.96.36.1991 for the BlackBerry Curve 8900.
