Previous reports suggesting that wireless carrier Sprint won't be carrying the iPhone 4 are partially correct -- the now free after contract phone won't be available at retail, and will only be purchasable online. A Sprint spokesperson told Cnet that the ""iPhone 4 will become a Web only device effective on September 21. We will certainly still be selling it." The original report showed that the older device would be "removed from Planogram on 9/21/12."
