Apple Store app gains the option to purchase iPhones without carrier pre-authorization
The Apple Store application that comes pre-installed on iOS devices has just received a small but important update, which adds a new option that enables consumers to bypass pre-authorization and activate later on full price purchases of iPhones on AT&T, Verizon, as well as Sprint. Obviously, you'll still have to activate with one of the US carriers after buying your favorite iPhone, it's just that you can do that later.
Also, Apple confirmed the update adds a scanner that should allow iOS users to add their credit card information at checkout much easier. Finally, the changelog mentions some iOS 11 enhancements, but no other details are available.
Keep in mind that aside from the iOS 11 enhancements, the rest of the new features are only available for customers in the United States.
