Seesmic released a short but sweet video that previews its upcoming client for Windows Phone 7. Similar to the iPhone version, the Windows Phone 7 version will support multiple pages of Spaces so you can customize the application to your liking. Right out of the gate, the app will support trends, directory, and search. Seesmic’s twitter integration is robust; the app supports messages, direct messages, lists, profile view, retweets, search, and geotagging. Facebook is also supported but the interface appears only briefly in this video preview. Check out Seesmic for Windows Phone 7 below in this official promotional video.
