iPhone 5 will have a 4-inch screen AND Retina Display.

A Korea Times report, , assures the iOSsphere that the iPhone 5 screen will be 0.3 inches or so bigger and support Apple's pixel-dense Retina Display technology.

But it won't support OLED, according to the KT story, citing as its source an "industry executive," because of brightness and power consumption issues.

ITProPortal editor Desire Athow isn't buying that last rumor. "That's a slight contradiction given that OLED displays are known to be power sipping rather than power gulping and Apple will have to up the resolution on a 4-inch display in order to keep up with the retina display pixel density, which currently stands at 326ppi."

KT also says iPhone 5 and iPad 3 will be released in the Spring of 2012; and the Next iPhone will have a quad-core processor.
