Apparently someone managed to get a hold of an internal inventory sheet from AT&T that shows the iPhone may be available in red. This goes quite nicely with Apple's other colorful devices, especially the Product (RED) iPod nano. I agree with Engadget's skepticism that the inclusion of a 4GB unit in the list makes us wonder about the inventory sheet's legitimacy (Apple has just stopped selling them, after all). Sure, a red cell phone isn't big news, but, well, it's the iPhone. In red, just in time for the holidays, perhaps.
