iPrivus is a new application that enables iPhone users to input any complete phone number and quickly receive the person's or company's name registered to the number. After receiving a call from a number not in your contact list, iPrivus will also help you identify who just called. The app can even be used to identify unknown calls on your home or business landline phones as well as numbers received via text message that carrier Caller ID services do not identify. In addition to the iPhone, iPrivus also works on a Wi-Fi-connected iPod touch. iPrivus is not cheap, however: iPhoners can purchase a year's subscription at the App Store for $44.99. Wow. See below for a video of iPrivus in action.
