You can adjust the image quality the TinyController displays on your computer to match your connection speed, which is handy while using bluetooth and wifi. You can also use the app to capture screenshots from your device from any app you're accessing.
To use TinyController you will need to install the desktop side of the app from the TinyController website, and the BlackBerry app from App World. The developer recommends you try the app before buying, so he has made a 14 day free trial available! If you choose to purchase TinyController after the trial ends, it costs $9.99 which is quite a bit less than similar apps.
