Want to get more affordable options in calling people overseas? Jajah, a VoIP service provider, just rolled out a useful application that can be used on Apple's iPhone and iPod Touch - yes, you read it right, iPod Touch - in order to make calls internationally.

Here's how the Jajah web application works: you just access Jajah's web address through iPhone and iPod Touch's Safari browser, enter your phone number and the phone number of the person you want to call. Jajah will then call you back, and will connect you to the other party.

Pretty useful? Quite, and helps you avoid going broke with all those international calls.
