Apple’s next slew of iPhones will go on sale in September, almost certainly less than four weeks from now. Before then, it’s probably under three weeks before all is revealed at the next keynote.

Apple usually sends out invites in late August, but history and habit suggest this year’s iPhone event will fall on September 9.
