That mysterious iOS 17.2.1 update released just before Christmas seems to be causing havoc for some iPhone users.
A couple of readers pointed me to a thread over on Apple’s support forum where users are complaining of having problems connecting to their cellular network following the update.
The problem seems to affect calls and data, and while the majority of complaints appear to be from T-Mobile and Verizon customers, the problem doesn’t seem limited to these networks.
