A few days ago, The Wall Street Journal reported that the next iPhone will have at least a 4-inch display, and the next day Reuters independently reported the same. Yesterday, Bloomberg jumped in with the same report, so it looks like it's a lock. In addition, Bloomberg is also reporting that Steve Jobs "worked closely on the redesigned phone before his death in October."

Interestingly enough, it was Steve Jobs himself who said that no one wants to buy a big phone. Of course, as we've seen with plenty of 4G LTE Android devices, larger smartphones are everywhere. Of course, Apple has some room on the current iPhone form factor to enlarge the display without changing the size of the phone itself too much. Maybe Steve was right--rather than making a big phone, Apple can just make a big display while keeping the device itself relatively the same size.
