The next generation Apple iPhone 6S release date has leaked many times and now it's appeared again in the most convincing leak yet.

According to the leak the iPhone 6S will be available to pre-order from 11 September for a release date of 18 September. The launch event is expected to happen on 9 September.

The leak appeared on French site Mac4Ever which was sent the photo of a network being given the dates by Apple. While the 11 September date is on show in the photo the site also claims to know 18 September is the shipping date.

Previous rumours have pointed towards that 18 September date also, so it now seems highly likely Apple is going with that day for release.

So far the specs of the iPhone 6S have been leaked only a little. We expect to see Force Touch added to the screen, the more sensitive tactile sensor found in the new MacBook and Apple Watch.

Also expected is the new A9 processor backed by 2GB of RAM. That might not sound much compared to phones now packing 4GB, but it's the most Apple has ever crammed into a phone. Currently the iPad Air 2 has 2GB of RAM, and that's blisteringly fast. The iPhone 6 only has 1GB of RAM.

The camera is also expected to receive an update with the addition of a 12-megapixel snapper on the rear.
