9to5mac is reporting that Apple has two iPhone 5 prototypes currently being tested that sport a “taller” 1136 x 640 Resolution; up from the current generation iPhone which runs at 960 x 640. The taller display now measures in at 3.95 inches corner to corner, up about a half inch from the current 3.5 inch display.

“These prototype phones are floating around Apple HQ in thick, locked shells in order to disguise the exterior design to “undisclosed” employees. We know of two next-generation iPhones in testing with a larger display: the iPhone 5,1 and iPhone 5,2.”

These phones are in the PreEVT stage of development and are codenamed N41AP (5,1) and N42AP (5,2). Because Apple reserves certain models for internal-only usage (such as the N96 phone we previously reported on), we’re not sure which of the two devices will make its way into the world later this year.
