A report in the Wall Street Journal claims that production of the next iPhone, dubbed the iPhone 5S, has already begun in time for its official unveiling this summer and that it will be joined by a cheaper version of the smartphone in order to increase the company's existing market share.
Rumours about both devices have been flying around since the end of 2012. However, when something appears in the Wall Street Journal or Bloomberg, it is taken seriously because, as well as a reputation for secrecy, Apple also has a reputation for ‘leaking' stories to those two papers.
