Uber Cab is an exciting new start-up that lets you order and pay for a private car from your cell phone. Uber Cab operates in the form of an iPhone app or via SMS, and is currently undergoing beta testing in San Francisco.

Being able to order a private car via text message or a simple application is definitely an awesome idea. Hopefully, Uber Cab takes off and expands nationwide, allowing individuals around the world to enjoy this luxury.
