There seems to be runtime instabilities to certain newer Blackberry Bundled OS updates. After much trouble running newer apps and updates with my current Virgin Mobile US Blackberry 8530 Curve. Most of which was occured a while after I updated the OS on my Curve 8530 from 5.0.0 bundle 1013 to 5.0.0 bundle 1675. Finally sick of having one updated paid app after another fail I started to contact the support for the paid apps and one in China wrote back I probably updated to an unstable OS version. Anyhow following downgrade instrucions at http://m.crackberry.com/how-downgrade-your-blackberrys-operating-system I returned my curve to bundle 1013. The apps now seemingly all work. So I figured this was important to post. If you upgraded your OS and are having problems (even a while after) you may wish to downgrade back to an earlier or even original OS.
