You may remember Microsoft’s Windows Phone “Insider” app as being a nice little something that was great for downloading Bing images for use as wallpapers. Well, now it has seen a big update for Windows Phone 7.5 which brings free Ringtone downloads. It also includes some tips about how to use Windows Phone in general along with some app and game recomendations. The update also gives the app a live tile and of course fast app switching.

If you’ve got the 7.5 update already, you’re looking for cool Bing wallpapers and new ringtones, you can download the new Insider app here.
