Apple will release an ‘iPhone mini’ with a 4inch screen early next year.
It is believed the handset will have a metal casing, but not the 3D Touch display of the current iPhone 6s and 6s plus.
The iPhone 7, which is unlikely to launch until at least September 2016, will be the firm’s thinnest handset to date at just 6mm thick.
This would put on a par with the iPod touch, and would be almost a millimetre thinner than the current iPhone 6.
Apple’s original iPhone, released in 2007, was 12.3mm thick. By comparison the current iPhone 6 is 6.9mm thick, while the larger iPhone 6 Plus is 7.1mm.
