Hot form the testing labs of the FCC (check the documents); it seems that Sprint is entering the iPod Touch case market with the ZTE Peel 3G router case. We all know how "amazing and magical" the iPhone is, but the monthly data charge plus the fact that AT&T doesn't offer the best service everywhere makes this device, the 3G case, I really great product. By the looks and specs of it, the iPod Touch should connect to it via Wi-Fi, like the famous MiFi type of products, also from Sprint and several other providers.
