Report: iPhone 6 to feature 4.8-inch screen

It’s no secret that Apple(s aapl) has been reluctant to introduce any dramatic changes to the iPhone form factor, increasing the screen from 3.5 to 4-inches for the first time only a year ago. The new iPhone 5s and iPhone 5c maintain that size, but a new report suggests that Apple could be working on something much bigger for the iPhone 6 – to the tune of 4.8 inches.

As noted by Boy Genius Report, in his latest research note on Monday Jefferies & Co. analyst Peter Misek increased his target on Apple’s stock shares from $450 to $600, noting, “Despite still seeing risk to CQ4 and FY13 revs, we now believe better [gross margins] will allow Apple to skate by until iPhone 6 launches with its 4.8? screen.” He adds, “We est ~50% of smartphone shipments have >4? screens and that iPhone 6 will catalyze a large upgrade cycle. The stock is attractive based on the attitude change, FY15 revs >+15%, and valuation.”

This of course isn’t proof positive that Apple is working on a larger iPhone, though Misek has proved to be a reliable source for Apple information in the past. But it jives with recent reports from the Wall Street Journal and KGI Securities, both of which claim that Apple is at work on a bigger iPhone.

On the other hand, Apple has probably been at work on a number of different size iPhones for years now. Whether it will actually releases one is the greater question, and perhaps most importantly: What would the resolution be? That would impact iOS developers. I highly doubt Apple will choose to enter the 5-inch and over “phablet” realm anytime soon, but I certainly don’t think a larger iPhone is out of the question.
