According to Engadget, this is a screengrab of AT&T’s inventory clearly showing an “iPhone 4S” on the system.

A helpful tipster sent us this tasty morsel, from AT&T’s internal system, listing the “iPhone 4s White” beneath a handful of already familiar Apple handsets. Could it be? Is Cupertino actually planning on bringing a white version of its next iPhone out at launch? We’re afraid only time will tell.

Apple is widely rumored to be announcing the iPhone 5 within the next few weeks, but rumors have also been circulating for some time that a mid-level prepaid smartphone – the iPhone 4S – may launch simultaneously.
