Silicone cases for the iPhone 5 have started to show up in AT&T stores according to an image received by MacRumors. The images, if authentic, set to rest the constant questions volleying back and forth over whether or not Apple will release a device called the “iPhone 5″ or just a device called the “iPhone 4S” this year. The cases suggest, as most reports have stated, that the iPhone 5 will indeed sport a thinner profile and a mute switch on the opposite side of the phone. In addition to Friday’s leak, on Thursday BGR exclusively published an image of AT&T internal inventory system that revealed an incoming stock of Case-Mate cases for the iPhone 5. BGR also published exclusive first images of the Case-Mate cases on September 15th, before the company quickly pulled them from its website. Apple will hold a press conference on October 4th in Cuperinto, California after which we will finally be able to put these rumors to rest.
