The U.S. Government has created several iPhone apps and mobile websites.  With the product recall app you can type in the name of a product and see whether it was recalled.  With the TSA app  you can determine whether an item is allowed in your carry-on or checked baggage, find out more about ID requirements and liquids rules, and other travel tips.  It also shows security line wait times by airport.  The Find an Embassy app allows users to find and contact the nearest U.S. embassy.
