According to that info, Apple will present the new version of its iPhone already in August this year, which is earlier than it was expected so far. It should be a 4.7 inch iPhone screen, if you believe the sources of the supply chain of the company. However, Apple should present another even larger model, with a screen diagonal of 5.5 (or maybe 5.6) inches.
According to the same source, sales will start in September. However, the planned production of the iPhone 6 this year will be about 80 million units, reports Economic Daily News, so Apple could once again face a demand that will be not fulfilled on time.
