How to uninstall apps on a BlackBerry Tour
Uninstalling an application from a BlackBerry Tour is a simple process that only takes a few minutes. First, find the app's icon. (By default, this icon will be located in the Downloads folder unless you've moved it.) Move the trackball over the icon and press the BlackBerry button (the one with seven dots to the left of the trackball). From the menu, select <span style="font-style: italic;">Delete</span>.<br /><br />A confirmation window will appear asking if you're sure you want to delete the program. Select <span style="font-style: italic;">Delete</span> again. You'll see a message that says, "Deletion will occur when handheld is restarted," and you'll be prompted to reboot your BlackBerry. If you choose <span style="font-style: italic;">Yes</span>, the phone will shut off and go through the cold boot process -- just like if you'd pulled out the battery. It may take several minutes for the device to fully boot back up, but when it does, the application will be deleted.<br /><br />If you choose not to restart at that time, the application's icon will be removed from the folder, but the application itself will remain on your BlackBerry until you perform a cold boot (turn the BlackBerry off, pull out the battery, then reinstall it and turn the phone back on).<br /><br />Even after you've completed the uninstall process, the application's files will still remain stored on your BlackBerry. You can find and delete these files by navigating through the BlackBerry's file system. In your Home folder, select <span style="font-style: italic;">Media</span> and then press the BlackBerry button. Choose <span style="font-style: italic;">Explore</span>, and you'll see two options: <span style="font-style: italic;">Media Card</span> and <span style="font-style: italic;">Device Memory</span>. Select <span style="font-style: italic;">Media Card</span>, then continue down the folder tree by selecting <span style="font-style: italic;">BlackBerry</span>, then <span style="font-style: italic;">app_world</span>, then <span style="font-style: italic;">downloads</span>.<br /><br />The next folder will have a name that's a combination of letters and numbers, which is your BlackBerry's PIN. Select this folder, and you'll see a subfolder with the name of the application you just deleted. (If you have more applications installed, there will be folders with their names here as well.) Press the BlackBerry button and choose <span style="font-style: italic;">Delete</span> to get rid of the folder, which is only taking up space and isn't necessary anymore since you've already uninstalled the application. If there are other applications here that you've previously deleted, you can erase their files too to free up more space.
