Rumors about the iPhone 6 release date abound, and today is no different. The Industrial and Commercial Times (via 9to5 Mac, which got it from what looks like a poorly translated EMS One), which is based in Taiwan, claims mass production for the 4.7-inch iPhone 6 will start in July, which would indicate that the release date for the handset would be within the typical September to October range.

The report also claims that the rumored 5.5-inch model won’t enter mass production until September, which could mean that Apple Inc. (NASDAQ:AAPL) will release it just in time for the holidays.

This iPhone 6 rumor holds nothing new

From the translation I viewed, it’s pretty difficult to tell exactly where the original Taiwanese source got its information from or whether it is pure speculation. This certainly isn’t the first time we have heard that Apple Inc. (NASDAQ:AAPL) is working on two larger iPhone 6 models. And it isn’t the first time we have heard that the release date for the larger version could be delayed.

In general, many have been expecting the iPhone 6 release date to be in September, simply because that’s when Apple Inc. (NASDAQ:AAPL) has launched previous models in the past.

Why the larger iPhone 6 could be delayed

Last year, there were reports that Apple Inc. (NASDAQ:AAPL) was having problems with the fingerprint sensor and the slightly bigger screen on the iPhone 5S which could cause its release date to be delayed. The company still managed a September launch, but it did so knowing that early supply of the handset was extremely limited.

This time around, it sounds like the larger screen has come back to haunt Apple Inc. (NASDAQ:AAPL) again, as reports suggest that problems with the in-cell technology on the bigger display may be the cause for the delayed release date. If Apple feels pressured to get both models out at the same time though, the company could revert back to thin film technology and simply use in-cell in the next model.
