FaceTime for iPhones is apparently being killed by a nasty Apple bug

A severe issue has been circulating among iPhone users, causing the iMessage and FaceTime apps to deactivate at random, with no means to reactivate them.

The information comes from a number of Twitter users, including well-known Apple leaker and Bloomberg reporter Mark Gurman

who have documented their experiences with the problem. This issue has only affected T-Mobile and Verizon customers thus far.

Verizon and T-Mobile have the largest service networks in the United States, which might be a huge issue with over 113 million iPhone users in the country.
