New Vonage Calling App for iPhone and Android

There is a cost associated with calling phones directly, but according to Vonage, the app offers international calling with per-minute rates that average 70 percent less than major mobile carriers and 30 percent less than Skype. This savings estimate is based on per-minute rates to the top 50 countries called. Billing is also more convenient, with payment integrated directly into your iTunes or Android Market account, instead of maintaining billing in a separate login.
