iPhone 7 design

Hottest facts:

Dust and water resistance
Two new black colors: 'Jet Black' and 'Black'
Camera bump remains

The iPhone 7 is just as sleek as its predecessors, with the iconic rounded design returning for a third instalment with the same 138.3 x 67.1 x 7.1mm frame as the iPhone 6S. It's lighter though at 138g, down from 143g on the 6S.

One of the big new talking points is its water and dust resistance, with IP67 protection bringing the new iPhone into line with the Samsung Galaxy S7 – and giving you peace of mind when you're in the bath or out in the rain.

Anyone hoping for a flush rear to the new iPhone will be disappointed though, as the iPhone 7 has a very noticeable camera bump.
