Apparently AppWorld is still having issues, so here is another update
New AppWorld version 22.214.171.124 available
Barely 72 hours has passed and RIM has posted version 126.96.36.199 of AppWorld. It is recommended that users experiencing any issues upgrade to this build by removing App World and installing the latest version.
HOW TO: On your BlackBerry device, go to Options > Advanced Options > Applications and scroll down to ?BlackBerry App World? so that it is highlighted, don?t click on it. Press the Menu key and delete the application. Then proceed on your browser to mobile.blackberry.com and download the AppWorld again
