'iPhone 7' preorders rumored to kick off on Sept. 9

Blass reported the supposed "iPhone 7" preorder date through Twitter without attribution. Last week, the blogger claimed Apple's next iPhone would ship out to stores the week of Sept. 12, or more specifically by Friday, Sept. 19.

"Confirmed: Pre-orders start on the 9th. You can extrapolate the launch event date from there," Blass' tweet reads.

The timeline is believable considering Apple in 2015 announced iPhone 6s on Sept. 9, opened preorders three days later on Sept. 12 and shipped out units a week later. Deliveries were initially scheduled to arrive on Sept. 25, though some lucky buyers received the device a few days early.

Apple traditionally opens preorders the Friday after a new iPhone is announced, suggesting this year's introduction might land on Tuesday, Sept. 6, or Wednesday, Sept. 7.

Unlike previous "tick-tock" iPhone product cycles, Apple this year is expected to carry over the device design language introduced in 2014 with iPhone 6. In lieu of a redesign, the company will reportedly incorporate updated internals like a faster processor, enhanced camera modules and, perhaps, the deletion of iPhone's 3.5mm headphone jack. Apple supposedly made the decision to stick with existing aesthetics as it waits for more advanced technology to mature.
