Apple has made no official announcement about the release date of this year's three new iPhone models but BGR Media feels confident that the announcement will be made September 12, orders will be taken beginning September 14 and the iPhones will go on sale September 21. But note that BGR's headline says "exactly" and the link says "basically." Hmm.
Yup, we know exactly when Apple's 2018 iPhones will be released
