And the next iPhone chatter keeps on rolling.

Over the last week the Wall Street Journal, Reuters, and Bloomberg have reported that the next iPhone will have a bigger screen. As previously reported by others, the WSJ and Reuters agree that the display will measure 4 inches diagonally; the current iPhone has a 3.5-inch display.

The new phone is also said to have a different design, and according to Bloomberg, the design was worked on by Steve Jobs before his death. According to their source, Apple has been working on this next iPhone even before the current iPhone 4S.

Analysts also predict that the new iPhone will be available with Verizon and AT&T LTE. The new iPad, which was released in March, was the first Apple product to provide access to the faster cellular networks.

Apple is expected to release the next iPhone in the second half of the year, perhaps in September, close to a year after the iPhone 4S was released. Apple has not said anything publicly about the next version of its iPhone.

Apple is also expected to show off the next version of the iPhone software - iOS 6 - at its WWDC conference in June. It is also expected to release new MacBook Pros with Retina displays during that time frame.
