May be linked to Apple servers
Some of Apple's various FaceTime-compatible devices made a series of random calls to each other overnight between the 27th and the 28th, according to reports and complaints on Apple's support forums. While the iPhone 4 was predominantly affected, the issue is also said to have hit the fourth-generation iPod touch, and even the Mac beta client. The calls are often described as showing mutual requests, even though no one actually dialed, and in some cases one of the devices was off.
The incidents are moreover said to have occurred at about the same time: approximately 6:30PM Pacific, 9:30PM Eastern and 3:30AM in central Europe. The exact cause is unclear, but could involve a problem on Apple servers handling the FaceTime system. Because of the involvement of Macs, the glitch is unlikely to be related to iOS 4.2.1, which was made public just last Monday.
