Apple Stores have been given the go-ahead to pricematch iPhone discounts from carriers and third-party retailers, a MacRumors source says. A chart supplied by the source shows Apple willing to provide a $49.01 discount on an 8GB iPhone 4 from carriers, RadioShack or Best Buy, and an identical amount off of 16, 32, and 64GB versions of the iPhone 4S sold by Sprint. With Target, only the 16GB iPhone 4S can be pricematched.
