Jajah is the latest to create a VoIP application specific for the iPod Touch. All you need is an iPod Touch and a decent WiFi signal, along with the Jajah application and you’re good to go. The appeal in such an application is the fact that there is yet one less difference between the iPod Touch and the iPhone. Granted the 3G network on the iPhone still reigns supreme when there’s no WiFi available (and when you actually have a 3G network signal). But having the option to make phone calls using your iPod Touch is certainly a benefit to those that would rather not sign their lives away to AT&T or hack their iPhone to work on another network.

Jajah isn’t the first VoIP service to create an application for the iPod Touch. Others, such as Truphone, have taken to the iPod Touch in order to extend their functionality across a myriad of devices. And that’s Jajah’s ultimate goal here as well. From PCs to cell phone integration, and onto the iPhone and the iPod Touch, Jajah is expanding the number of devices on which you can access one of its many services.
