Three sizes
Apple is rumoured to be working on three versions of its next iPhone, including a 4.7-inch iPhone 7s, a 5.5-inch iPhone 7s Plus and a 5.8-inch iPhone 8.
While early reports suggested that all three models would boast identical specifications, it's looking increasingly likely that the larger iPhone 8 model will be significantly more advanced than the 7s and 7s Plus - which are expected to closely resemble the iPhone 7.
