If your phone is Android-based, you need to go to Menu > Settings > Applications Manager and manually tap on each of the application you want to uninstall. Once the page opens, you can tap on Uninstall and follow instructions. In iOS, to remove the app, tap on the program, then you click the "-" sign. For the rest of the operating systems, the procedure is the same, you can uninstall programs from Application Manager or by keeping the finger tapped on the app until a menu appears.
