Google offers a very handy tool that's perfect for the road warrior. And you don't need any fancy phone to do it—just send a text to 466453 on your mobile phone (a text messaging-enabled mobile device with a text messaging plan is required) and, based on your query, Google will text back helpful results. But make sure you check your carrier's plan—this service is free from Google but charges from your carrier for text message usage may apply.
