Apple's iPhone 6 will jump in screen size to almost 5 inches from the current 4 inches. At least, that's the claim from Cantor Fitzgerald analyst Brian White.

After meeting recently with an Apple supplier, White expressed confidence that a new big-screen iPhone will emerge next year, as reported by Boy Genius Report.

"Our meeting with a tech supply chain vendor highlighted a bigger iPhone is in the works, and our contact expects a launch in the 2Q:14/3Q:14 time frame," White said in an investors note released on Thursday. "Nearly a year ago, our research in Asia uncovered early stage work on a larger iPhone, and we indicated in our Apple initiation report dated 9/4/13 that 'a larger screen size on the iPhone is possible in 2014 that could approach 5 inches.' Given today's meeting, we are confident that a larger iPhone (approximately five inches) will become a reality in 2014."

White's prediction follows a similar claim from Jefferies analyst Peter Misek that the iPhone 6 will sport a 4.8-inch screen. Misek's forecast followed a meeting between him and Apple suppliers in Asia. DisplaySearch analyst David Hsieh also is eyeing a larger screen for next year's iPhone, specifically one that's 4.7 inches.
