On the heels of word that a smaller version of the iPhone is in the works, another report has emerged that has the fifth-generation smartphone will actually feature an expanded screen to take on Android devices' larger screens.

The new iPhone, which is expected to be released this summer, will feature a 4-inch screen and is already in testing, according to a Digitimes report that cited unnamed component suppliers.

The report of a larger screen is just one among many regarding the next iPhone that have materialized in the past couple of days.

Bloomberg reported Friday that Apple was working on a new line of iPhones, one of which would be "cheaper and smaller than the most recent iPhone." That report, which cited a source who had seen a prototype, also pegged Google's mobile operating system as the intended target for the new device.

The Wall Street Journal published a similar report Sunday, adding that Apple was considering using its MobileMe as a digital locker where iTunes users can store electronic books, songs, and movies. If, as rumored, Apple were to cut the iPhone's memory to reduce its size, it stands to reason the company would augment that lost storage with online locker where users could keep media, calendars, address books, and e-mail on Apple's servers.

Meanwhile, a Taiwanese blog, Apple.pro, says it has its hands on information pointing to three different models being considered for final production as the iPhone 5. One has a physical keyboard that slides out, and another is said to be like an iPhone 4 in styling but with a longer-lasting battery and a better camera.
