Have we got something here for you, after OS 5.0.0154 appeared in the forums fro the BlackBerry Storm 9530 our mate TimBuk2 has sent in some BlackBerry OS download links for the Tour, Bold and Curve 8900.

The Tour version 5.0.0.140 is a bit old now but OS 5.0.0.190 is hot, very hot for both the Bold and the 8900 and makes some big leaps forwards including the appearance of threaded SMS as shown in the picture.

At last a native threaded SMS client on the BlackBerry that’s not all some other cool features include theme previews upon downloading and a few others for details on the other versions be sure to visit the Storm OS and Beta OS forums. As always this is an unofficial release and if you choose to install you do so at your own risk. Source – crackberry.com
