We already knew T-Mobile had big plans for the iPhone in coming months when it announced plans to launch the Unlimited & Unlocked iPhone marketing initiative on the same day as the iPhone 5 launch. Today, we get confirmation from TmoNews that nano-SIMs are indeed on the way to T-Mobile for customers wishing to use the new iPhone on its network. The carrier expects the SIMs to arrive in October, but we are hearing they have already started arriving. You will, of course, first have to get your hands on an unlocked iPhone 5.
