The iPhone 6 has had one final full leak just before its official unveiling on Tuesday (Sept 9), Digital Spy said.

Outed by China Mobile, the handset full spec sheet is now out in the public domain. It includes a 4.7-inch, 1134 x 750 resolution screen covered in sapphire glass.

The camera unit is an 8-megapixel affair, with a 2.1-megapixel option on the front. Other features include iOS 8, as well as four different storage options, going from 16GB all the way to 128GB.

One previously-not-mentioned rumour is that the handset is both waterproof and dustproof. It's also 138 x 67 x 7mm in size, which makes it exceptionally thin.

China Mobile has posted September 19 as a release date for the device.
