White House launches iPhone app

Want to watch President Obama's State of the Union address on the go? The White House has launched a new iPhone and iPod Touch application that will, among other things, make that possible for some cell phone users.

In a blog post, Whitehouse.gov said the new application would allow users to check for updates, watch videos and Web chats, and do some research. The blog noted that mobile Internet use has doubled over the last year and has become a more important means to receive information.

A mobile version for other cell phones will also be available in coming weeks, the blog post said.
