Hey, I'm having a problem with my app world. The icon is in my tray but when I click on it nothing happens, it just won't open. I've done a battery pull and deleted and reinstalled it! Help!
Try connecting your BB to your PC and desk top manager. Sometimes this will correct problems like this as it will reinstall missing core apps. It does not always work. Worstcase you will need to do a security wipe and reinstall the whole OS.
