Apple may delay the introduction of the iPhone 5S until the end of the year after the design was changed to feature a bigger 4.3-inch retina display screen, Bloomberg reported.

While this remains in the rumor department, it seems awful last-minute to me.

Jumping to 4.3 inches makes sense based on the rumor’s we have at hand, mostly that a budget iPhone is expected. The larger iPhone could easily be the premium while the current phone would become the budget phone. At least that’s what I expected all along. I have assumed that a larger screen iPhone was just one of many things Apple wasn’t discussing.

Bloomberg has not been able to get a response and we don’t expect they will get a definitive answer.
