iPhone 4G Rumors Visualized [CHART]
An OLED display, 5-megapixel camera and a release date between May and July appear to be the most likely rumors (and we agree that those all sound like very distinct possibilities). Also ranking high are rumors of a front-facing camera, dual-core processor with more RAM and a touch-sensitive case.
As for the removable battery rumor, 60% likely or not, we don’t see that happening. Apple has moved its portable line to built-in batteries; it seems unlikely to us that they would add a removable battery to the iPhone.
