Considering that last year, Apple released two different models of the iPhone at the same time with the Apple iPhone 5s and Apple iPhone 5c, there is no reason to think that it won't do it again this year. But instead of focusing on two models differentiated by price, this year the difference between the two models should be in the size of the screen. The Apple iPhone 6 screen is expected to be 4.7 inches, .8 inches smaller than the phablet version. Its dimensions are believed to be 162.8mm x 85.4mm x 7mm.
You can check out a series of photos below, showing how the mockup of the 5.5 inch iPhone phablet was created using a 3D printer. You can also see more comparisons between the mockup and the Apple iPhone 5s, all by clicking on the slidescreen below.
