Jajah uses devices to grow

VoIP-based callback startup Jajah has been promoting its growing list of compatible mobile devices lately — the LG Prada, and promises of the iPhone, as soon as its available. Many devices with an Internet connection and a browser shouldn’t have too much trouble connecting to the mobile web-based service. Today the company is going after connected gaming devices and points out its calling service works with Sony’s PlayStation Portable.

Like with other mobile connected devices, Jajah users can just use a browser on the PSP and an Internet connection to go to mobile.jajah.com and sign into their Jajah account. User’s address book contacts should show up as links for click-to-call or users can enter in new numbers. The company which has offices in Israel, Mountain View and Luxembourg, says it is currently testing to see if the PlayStation 3 and PS2, Xbox 360 and Wii are compatible, too.

Jajah has been hoping to decrease their reliance on the PC, and is reported to be working on Jajah-enabled handsets with a consumer electronics companies too. Maybe the mobile device push also has something to do with the company’s reported IPO dreams. The company recently said that it had two million registered users, and adopted an ad-supported free calling model in some parts of the world.
