With all of the recent iPhone 5 case leaks, people have been debating whether or not Apple will be making a radical design change with the next generation iPhone. Among the most disputed and want additions that people want with this next generation iPhone is whether or not the iPhone 5 will contain a 4-inch screen to compete more comparably to the massive Android devices.

According to recent rendering commissioned by MacRumors, the next iPhone will more than likely have a 4-inch screen.

From 9to5Mac:

If these cases are correct (seen after the break), they point to the iPhone 5 packing a larger 4-inch screen, compared to the iPhone 4′s 3.5-inch. But, earlier reports contradictMacRumors, saying the iPhone 5 will feature a screen closer to 3.5″.

You may remember our case reports from July which showed the iPhone 5 having a longer and wider design. Macitynet.it also posted their case findings yesterday, which match up closely toMacRumors’ and 9to5mac’s findings. But again, there are those who claim the iPhone 5 will have a 3.5″ screen.

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.
