MacRumors has posted about the iPhone 5 possible design , this concept design with measurements 4.33″ x 2.36, which compares to the iPhone 4′s dimensions of 4.5″ x 2.31″.
If these cases are correct, they point to the iPhone 5 packing a larger 4-inch screen, compared to the iPhone 4′s 3.5-inch. But, earlier reports contradict MacRumors, saying the iPhone 5 will feature a screen closer to 3.5″.
At any rate, why would case manufacturers begin spending millions of dollars to build these cases without any definite knowledge? Could the 3.5-inch design be the iPhone 4S and the iPhone 5 be slightly larger than 4-inches? Apple is expected to announce the iPhone 5 later this month, and the phone is planned to go on sale either October 7th or October 14th, with pre-orders starting around a week before.
