Some AT&T customers with iPhones noticed something weird earlier this week. Those who had installed a new beta version of iOS reported seeing "5GE," rather than "4G" or "LTE," in the upper right-hand corner of their screens, according to The Verge. But Apple doesn't sell an iPhone that supports 5G standards, and AT&T doesn't yet offer 5G service for mobile phones.

In fact, what those customers saw was a bit of AT&T marketing. AT&T has branded parts of its 4G network as 5GE, or "5G Evolution." Apple has apparently added that branding to the latest version of its mobile operating system, but doesn't mean that anyone's connection is actually faster because of it.
