Well, here's a nice bit of symmetry to emerge from the Apple rumor mill in recent days -- some new purported details on both the rear and front-facing camera on the next-generation iPhone. The first, and more straightforward of the two, comes courtesy of The Chosum Ilbo, which is reporting that the next iPhone will pack a 5-megapixel camera supplied by LG Innotek. Details on it are otherwise pretty light, but the site says that LG has already started producing the "sophisticated cameras" at its plant in Gumi this month, with mass production supposedly set to begin in the second half of this year. The second rumor concerns the iPhone's front-facing camera, and comes after a bit of digging in the latest iPhone 4 SDK beta. According to MacRumors, the SDK not only includes an unfortunate bit of code that suggests video calls will be WiFi-only, but evidence that video chat will be integrated into Apple's Game Center as well -- exactly how remains unclear, although there's certainly no shortage of possibilities. Dive into the links below for the complete details.
