Seesmic, the popular social networking client for Windows Phone, has been updated to version 2.0 and finally adds Mango support. Quick resume and performance improvements join the introduction of multiple live tiles, which will allow the user to pin Twitter timelines (and more) to the home screen. Should this app be too feature-rich for your liking, there are more simplistic solutions available such as Mehdoh.

You can download Seesmic from the Marketplace.
