Apple could be out with a 4.7-inch iPhone 6 as early as June

Chinese analyst Sun Chyang Xu has reported that Apple plans to release an upcoming iPhone 6 model with a 4.7" screen this June, with production expected to get under way in May. Unfortunately, it will retain the 1136 x 640 pixel density of its current iPhone 5s flagship.
This confirms earlier gossip coming out of Apple's supply chain regarding two upcoming iPhone 6 screen sizes. Additionally the additional information regarding the production and release dates makes sense, as it would coincide with Apple's WWDC on June 10.
Two major iPhone variants would also fall in line with Apple's new release cycle of two devices per year, which it introduced this year with the iPhone 5s and 5c.
