The last time I checked, the most recent official software for the BlackBerry Curve 8900 was OS 184.108.40.2061. Optus Mobile are now listing OS 220.127.116.111 for the Curve 8900 so it might be worth checking out. Let us know if you see any major or minor improvements.
Download OS 18.104.22.1681 for the BlackBerry Curve 8900.
