Apple unveiled a new line of iPhones. The company unveiled four new models, keeping pace with the past few generations: the iPhone 15, 15 Plus, 15 Pro and 15 Pro Max. Like last year, the entry-level models start at $799. The Pro version will remain $999, but the Pro Max will now begin at $1,199 — up $100 from last year’s installment. Ed Ludlow reports.
