Over the years there have been quite a few apps that let you control your BlackBerry from your PC. The latest to come to my attention (thanks Jaybo!) is TinyController by CompactByte. TinyController simply gives you no frills control of your BlackBerry smartphone from your PC or Mac through a USB, Wi-Fi, or Bluetooth connection between the devices. The app is also focused on speed instead of features which is a different spin.
The best part is that TinyController offers up a 14 day free trial for you to give it a spin. This is because not all apps can work over such an app like BBM Groups so you should definitely try it out before you make the plunge. You can read more about it at www.tinycontroller.com or pick it up in App World for $9.99.
