Official iPhone 7 presentation Video. Iphone 7 release date 2016.

When is it out? Likely September 2016
What will it cost? Probably the same as the iPhone 6S
iPhone 7 release date: If we were betting people we'd say the iPhone 7 will probably arrive in September 2016. Apple tends to stick to a schedule, and the last few iPhones have all been launched in the month of September.
suggestion of a waterproof iPhone 7 comes from the Apple supplier Japan Display. That's always an issue with waterproof phones such as the Sony Xperia Z line, so the fact Apple's main supplier is looking to stop the problem may be a big hint at what the iPhone 7 will do.

Another report has suggested Apple will opt for a slimmer phone rather than a waterproof iPhone 7. Apple will likely get a new LCD display technology as well, which will allow the iPhone 7 to be 1mm thinner than before.

iPhone 7 screen
Apple is apparently likely to move to glass-on-glass screens, which in turn opens up the possibility of a QHD or even a 4K display. A jump in resolution might not be the only way the iPhone 7 imitates Android.

New Iphone 7 is just a few months ahead.
