The App Store has come to Facebook. You can install the App Store App and then browse all the Apps that populate the iTunes desktop app, your iPhone or iPod Touch. When you want to download an app all you have to do is click it and then iTunes will open and allow you to download that very app. Yes you could browse iTunes itself, but now that the App Store can be integrated into your Facebook page, you can save desktop resources and keep within Facebook all at the same time. Check it out for yourself.
