You should be able to uninstall via Blackberry Desktop Manager > Add/Remove Applications
Just search through the list and untick or tick the box until in that row it says "uninstall" and then click next, make sure it's uninstalling it and click finish- the desktop manager will take care of the rest.
If you can't remove it that way, hover over the icon on your blackberry and click the menu item and click "delete"
This may prompt you to reset your device to fully delete it- which I suggest that, if it does come up, you allow it to.
Best of luck!
