iPhone 7 hits stores across U.S. — but some models are already sold out

PHILADELPHIA, PA – Since 8:00 p.m. Thursday night, iPhone 7 customers waited in line at the Apple store on Walnut Street, anxious to get their hands on the latest product from the popular tech giant.

However, Apple has already warned customers the new Jet Black iPhone 7 is already sold out, and the iPhone 7 Plus is already sold out in every color.

Apple said they've already run out of their initial batches of the phones during the pre-order period. They won’t be available for walk-in customers for the official release today.

The new phone features a thinner design, souped-up cameras and a new headphone jack with wireless headphones.

The iPhone 7 starts at $649 and the 7 Plus will run you $769.

Some customers at the Center City Apple store said they were buying the phones to take overseas to sell in countries where they have not yet been released.
