In my Blackberry 9800, app world 188.8.131.52 is installed but not working.
error message says - "Blackberry App World is undergoing maintenance. Please try again later"

Personally I never recieved that error ever , meanwhile try a battery pull restart by removing the battery while your device is Powered On ,after reboot please visit app world and see if you are able to visit app world.
