Yes, it's true. Internet telephony company Jajah is participating in the iPhone Developer Program. That means in addition to its existing web-only client, there will also be a native VoIP app for the iPhone this summer.
You can expect the new client to be available via the App Store, which is launching sometime in June.
If you recall, after a lot of speculation about what would and wouldn't be allow to run on the iPhone, Steve Jobs said VoIP would be permissible at the SDK roadmap event last March, but that mobile carrier networks were off limits.
The exact wording from the SDK agreement is as follows: "If an Application require or will have access to the carrier network, then additionally such Application: …May not have Voice over Internet Protocol (VoIP) functionality."
Pretty clear cut. Jajah is apparently adhering to this stipulation, which is almost certainly tied to the contracts Apple has with AT&T and other individual carriers in Europe. The compay says the new native app will either be free or a low-cost service, depending on the call destination or source. At the very least, it's going a be a great option for jet-setters who want to avoid those ridiculous roaming charges.
