I am going to introduce very useful app for your blackberry. It is Blurts. Certainly it is not a, yet another app. Blurts is a tool that enables you to control your Blackberry through your PC.
It has very good, exciting features. With Blurts, now, I can make a call from my laptop, I can attend / ignore call through my laptop, send SMS, grab the screen image of the BB etc. Now phone calls are not disturbance, when I work with my laptop. With blue-tooth headset connected - its a fun to have conversation while your hands are at work.
Of course, it has some bugs. Rarely, it is not getting connected easily, requires a restart of the app. The usability of the PC interface can be improved a bit. Otherwise, it is no nonsense app, works fine with me for the past two months.
One more important point - you need to pay for the Pro version. Paying couple of dollars will not be a matter considering the features offered.
