Hot off the heels of the Android Market web store, RIM has announced an update for their own app store, the BlackBerry App World.

BlackBerry App World

BlackBerry App World 2.1 is now live, and intros in-app purchases, a feature that’s still forthcoming for Android apps. It also comes with a modified layout for Featured Items when viewed on a BlackBerry smartphone. Featured Items are now filtered by carrier and country making it easier to view the most relevant items per user. Subtle changes, but good ones nonetheless.
