Apple is set to unveil its next-generation iPhones at an event on Sept. 9.
The tech giant is expected to release a pair of larger iPhones running faster, "A8" processors: one with a 4.7-inch screen, and one 5.5 inches. The compares with a 4-inch display on the iPhone 5S.
It remains unclear whether or not Apple will launch one or two new iPhone 6 models this time around. Expectations are already set for a 4.7-inch model as well as a 5.5-inch model. However, there have been reports that the 5.5-inch model is facing production challenges, a common storyline when it comes to new Apple products. As a result, it's possible that Apple may not launch the 5.5-inch iPhone until later this year.
