Please remember that not all the apps are going to be released at one time. RIM will be releasing them gradually between October 19 and November 30. Users with a BIS Lite or BBM-only plan will be able to download the free apps over wifi from App World starting in November.
You can find more details on the BlackBerry Facebook account including some of the fine print regarding this deal.To find the free apps, simply open up App World, and you should see "A Thank You Gift" in the carousel, as seen in the picture above. (If you don't see it yet, or don't see any apps listed when you open it, try refreshing App World by typing Alt + R,S,T,R,S,T in the main page, or just Alt + R,S,T in the My World section.)
