Well, it's kind of a marketing term (4G). It's HSPDA+ on T-Mobile which can be thought of as 'enhanced 3G'. It's faster than 3G but not as fast as LTE.My bad, so im guessing in Euroland its different.
On my 4s i can only 'Enable 3G' under Setting\Cellular, even though my carrier supports 4G\LTE.
PS - So nice to see old iOS (6, right?)![]()
As to iOS 6, it was nice while it lasted. But my son, who is unfamiliar with jailbreaking decided he wanted to sacrifice that for iOS 9.3.5 and the ability to use later version apps.
As much as it pained me I updated him.
