A mobile app ... from the Internet Revenue Service? Hey, don't laugh. IRS2Go is a convenient way to find out the status of your tax refund--assuming you're getting one, of course. The app also offers an easy way to subscribe to IRS tax updates via email, and to the IRS News Twitter feed. The tax collector's free app has IRS contact numbers for individual filers, businesses, other organizations--and even for victims of identity theft. Don't worry, there's no Audit button.
