Many of the rumors so far seem to be pointing to an iPhone 4-like frame for the new iPhone 5. Looking back at old rumors, an iPhone 5 parts video that surfaced back in January may have actually been an early look at the iPhone 5 casing (photo above).
That video actually first revealed the new antenna dividers found on the Verizon iPhone, but also included a SIM card slot that does not appear in the Verizon iPhone. It's believed that the iPhone 5 may support both CDMA and GSM networks in one phone. The Verizon iPhone has already been found to use a Qualcomm chip that can support both networks.
