Jajah iPhone telephony
Jajah today announced it is in the process of expanding its iPhone call-back service into a full-blown global Voice over IP application, in addition to its current web-only client. According to Pocket-lint.co.uk, the iPhone application will be available in the summer, following shortly after the impending iPhone 2.0 firmware version and the app store. The VoIP application will allow both incoming and outgoing calls over WiFi, and will be either free or a low-cost service, depending on the call destination or source.
