Apple open free Facetime call centre
Some people are calling Facetime the most magical feature of the iPhone 4 and iOS 4 and it may be. Apple are certainly taken with it, having gone so far as opening it as a video chat standard. If you aren’t a dev though, Apple have a special number that you can try out to test the video/audio quality of Facetime.
Here it is: 1-888-FACETIME (322-3846)
