Double leak confirmed previously rumors and speculations about the design of the upcoming Apple iPhone 7.

According to Tampa Bay Review, Apple Inc.'s CEO Tim Cook has previously hinted on the release of iPhone 7 in this year, 2016. However, it seems that, according to recent reports, consumers might have to wait longer for the release on the upcoming Apple flagship device, despite the earlier announcement made. The iPhone 7 is currently undergoing a major upgrade.

Recent leaks online suggest potential differences in the new mobile's design. It seems now almost certain that the upcoming release of iPhone 7 will not come with a headphone jack. It is also clear that will be in fact two releases, the iPhone 7 and the iPhone 7 Plus.

The production of the upcoming device is expected to start in July, while the release announcement will be made in the month of August or September. The iPhone 7 will feature certain specs that are almost certain, based on the previous leaks and speculations.

Apple is well-known for its ability to keep the specs and design of its upcoming devices a secret. However, consistent leaks suggest that the company's upcoming iPhone 7 may be more controversial than expected.

Different Apple accessory retailers who produce iPhone 7 cases have approached the publications Forbes and MacRumors. The missing of the headphone jack is now almost certain because both the physical cases analyzed by Forbes and MacRumors show no dedicated cutout for the accessory on either the bottom or top of the iPhone 7.

Instead of the headphone jack, the more symmetrical design will place a Lightning port in the middle, while allowing on either side for a pair of speakers. According to supply chain sources, Apple is still testing variants of iPhone 7 with both single and dual speakers.

Another aspect noted in both leaked case designs is the presence of the dual camera setup in the iPhone 7 Plus. Unfortunately, the iPhone 7 will not be getting this feature but a much larger single rear sensor.
