We have all been waiting on an iPhone VoIP (Voice over Internet Protocol) solution, since we heard that Apple would allow VoIP application access while connected to WiFi. Fring has finally made our dream a reality -- and it's a reality that's available today!
Fring is a new, free iPhone application that integrates with Fring's network and allows access to the following IM/presence services:
In addition to simply chatting with buddies from the above services, you can place VoIP calls to other fring users, or using Skype/SkypeOut or another SIP provider (Gizmo, Vonage, etc.). We'll take a more in-depth look/review this weekend -- so be sure to stay tuned to TUAW. In a quick test, I was able to call Skype users from my iPhone and carry on a (slightly echo-y, but perfectly audible) conversation.
You can download this application today by visiting the iTunes App Store. The application weighs in at 3.0 MB. You can also get more information about this service and the application on the Fring website.
