Engadget has released their Windows Phone 7.5 app and  has been updated to support the new features in Windows Phone 7.5 like multitasking, landscape mode and Live Tile support . This allows you to use the built-in Podcasting feature to play podcasts in the background and some fancy new Live Tile goodness.

There are also some social features to share posts using Facebook, Twitter, Tumblr, Evernote, Instapaper and Read it Later.

You can find the app right here, or just look for it in the Marketplace.
