iPhone 4 users receiving random FaceTime calls that were unable to connect at all hours of the night after upgrading to iOS 4.2.1. Over 40 users of iPhone 4, on Apple's Discussions message board, reported having experienced this issue.
One major round of false FaceTime calls went to the United Kingdom between 2 A.M. to 2:30 A.M, causing much unrest, annoyance, and concern, especially as all of the calls originated from someone in the contacts list of the phone. Users in other parts of the world reported similar issues all at the same time as the UK users, who seem to have been hit the hardest by phantom calls.
One user mapped out all of the times reported by the users who've complained. "It does seem to be the same time across the world, 6:30pm LA, 9:30pm NY, 2:30am London, 3:30am Europe. What was Apple doing?"
FaceTime maintained by the Apple. There seems to have been a server blip, but with such extraneous results it isn't clear what caused the rude awakenings. But, the issue wasn't contained to that one blip at 2:30 A.M. in the UK, before that night, other users were also experiencing similar phantom FaceTime calls, most of which are related to iOS 4.2.1.
