When Apple announced iOS 7 last year, it was met with both heavy praise and criticism at the same time. Those who praised it said that it was about time that iOS got a makeover, and those who criticized it felt that the changes were too drastic and that the design was a little too colorful for their liking.
That being said if you are on the latter side of the fence and are refusing to update to iOS 7 because you don’t fancy its design, you might run into issues especially if you’re planning on using FaceTime. According to a recent support document released by Apple, it seems that there might be issues with FaceTime for those running on older iOS builds.
According to Apple’s support document, it reads, “If you started to have issues making or receiving FaceTime calls after April 16, 2014, your device or your friend’s device may have encountered a bug resulting from a device certificate that expired on that date. Updating both devices to the latest software will resolve this issue.”
Oddly enough it seems that this issue does not affect iOS 6.1.6 or iOS 7.0.4. For those using FaceTime on their Mac computers, this should not be an issue either as long as you’re using OS X 10.9.2 or later, Snow Leopard 10.6, Mountain Lion 10.8, or Lion 10.7, assuming you have the latest security updates installed on your computers.
