In this episode of the Windows Phone 7 App Roundup we demonstrate five applications in 30 seconds each. These apps will keep you entertained, allow you to share and edit your photos, and update your Twitter status on the go. To download these apps directly to your WP7 device, just click on the title of the application and the Zune software will automatically launch to the app in Marketplace. If you have the free Microsoft Tag app installed on your WP7 smartphone just snap a picture of the Tag image and the mobile Marketplace will navigate to that app.
