First, make sure it hasn't inadvertedly been hidden. While on your homescreen, press the menu key and select Show All or Unhide All, whichever is available. If your icon was just hidden, this will make it reappear and you're welcome for the help.
If it's not just hidden, you'll have to reload the app. Start by going to your Applications list and finding App World. Your Applications list can be found by following on your homescreen Options>Applications OR Options>Device>Application Management (depending on which OS your phone is running). Highlight the app, press your menu key and select Delete. Once it's gone and you've rebooted your phone, you can type in your phone's browser www.blackberry.com/appworld to reload it. Hopefully that will bring back your icon.
Let us know if that helps you.

OK, delete it once again then plug your phone in to your PC and open BlackBerry Desktop Software. Once your phone has connected, click Applications on the left column and look for App World. If it's there and has a plus " + " sign beside it, click the plus sign to load it that way.
Please post back with your results.
