Is there a free API or some other way to determine what carrier a cell phone number is registered with?
I'd like my application to broadcast text messages without them picking their carrier from a list.
UPDATE: Interestingly, a coworker found the answer: http://developer.whitepages.com/
UPDATE2: Well the whitepages license agreement is so restrictive that you can't build an app for it. Any other ideas?
