Rumors are circulating about the new iPhone 6 screen once again. Now, some suggest a 5.5-inch screen could be in the mix.

The debate sparked late last week, according to at least one report, given news of an iPhone with an even bigger screen than previously anticipated. There is little evidence to go on, other than some leaked images of a printed circuit board. Apple has kept its lid tight, making the speculation and rumors all the more juicy. A 4.7-inch screen already made headlines and the rumors about that amassed strong levels hype and attention surrounding the awaited iPhone 6.

A logic board appeared in a set of photos that leaked and made it online. Chinese sources reportedly leaked images and said that the larger phone would also feature enhanced WiFi networking chips. Images containing other components were also included in the leaks.

Questions remain to be answered, however. One obvious one would be why Apple would even want to release a phone that is bigger than an already bigger phone. If Apple expects sales to increase with the 4.7-inch, then what is the reasoning behind the 5.5-inch? One possible answer is in the far east, Asia. Asian customers have shown to have a preference for working on larger screens, as reports suggest.

Other clues have also surfaced in reports, such as an "iPhone 6 Air" case that appeared online. The iPhone 6 air cases were made available for pre-order on Amazon.

The new phones could make appearances by September via Apple and even make it to stores by December in time for Christmas, according to another report. Though "phablets" are popular in Europe in Asia, it is unclear whether or not many units would sell in the United States.

Also, alongside these iPhone 6 rumors, are those about the so-called iWatch, an anticipated smartwatch from Apple. Apple recently was granted approval for a patent on a wrist-worn "iTime" device, but who really knows which, if any, will be Apple's entry into the wearable market. Samsung has already released a couple models powered by Android.
