While we patiently await the arrival of the sixth iPhone, Apple is still deciding which test model will be the one released later this year. In total, there are at least two prototypes floating around the Cupertino, California campus in “thick, locked shells in order to disguise the exterior design,” according to 9to5Mac.

According to “independent” sources, the two known prototypes are code-named N41AP (5,1) and N42AP (5,2), respectively. Each model includes a 3.95-inch display. Additionally, each includes a resolution of 640 x 1136, or an extra 176 pixels vertically versus the iPhone 4S/4.

To take advantage of the new pixels, Apple is said to be testing builds of iOS 6.0 that allow for a home screen with a fifth row of icons, and “extended application user interfaces that offer views of more content.”

Plus, while the new phone’s screen could be the same 1.94 inches wide, it would grow to 3.45-inches tall. As such, the new resolution would be close to a 16:9 ratio.

Finally, both prototypes include a physical home button and a smaller connector.

These latest rumors are similar to others we’ve heard about Apple’s next handset in recent months. The most significant news here, assuming the report is correct, is that Apple has yet to decide on which iPhone model will go into production. This once again suggests the next model will arrive in October and not at next month’s Worldwide Developer Conference.
