Are you sure you deleted the entire application, or just the icons? If you accidentally hid the icons, you can fix that. As far as re-installing the applications, I would first go under options-advanced options-applications. It will load a list of your currently installed apps. If you don't see those apps in the list, I would do what the previous poster suggested and try loading them from the Blackberry Desktop Software. I'm new to my BB flip, so I hope you find out how to do this from someone who knows more than me!
