Sprint has the iPhone 4S. Or something.

"Sources" that a version of the iPhone intended for Sprint is right now in "advanced testing." This is being done in Apple's sinisterly-but-coolly-named "Black Labs," presumably a reference to office space and not dogs.

Could it be the iPhone 5? "The physical design of this device is akin to the iPhone 4 of today, so this might be the iPhone 4S device with support for all carriers that we have been dreaming up and hearing whispers about." Unless you're Beatweek.

But there's more -- a second iPhone for Sprint that will support 4G, however that's defined by this month's TV ads: "Sources also say that talk of a 4G variant of the iPhone for Sprint is moving along, but the first generation Sprint iPhone that is currently in testing does not feature support for 4G bands."

So apparently the first Sprint iPhone will be the iPhone 4S, and the second Sprint iPhone will be the iPhone 4S 4G, which means the third Sprint iPhone will be the iPhone 5, which may or may not be 4G, because that would make it the iPhone 54G.
