Tim Cook to unveil new iPhone models today: Here's what to expect

On Aug. 2, Apple Inc. became the U.S’s first publicly traded company to sustain a market valuation of $ 1 trillion. But today, Sept. 12, is actually Apple’s most important day of the year.

At 10 a.m., Tim Cook will take the stage at the Steve Jobs Theater in Cupertino, California, to unveil the company’s iPhone and Apple Watch strategy for the next year. Individually, each new phone isn’t a significant upgrade. They’ll all look and act like the iPhone X, except there will be two bigger versions: a premium model selling for about $1,000 and another that costs less.
