A ZTE-made case for the iPod touch called Sprint Peel is making rounds at the FCC. The music player received an update to iOS 4, and this case is allowing it to connect to Sprint's 3G network to use its data services while on the go. Besides serving as a sleeve, it turns the iPod touch into a Wi-Fi hotspot as well.
There is no word on the pricing just yet, but it seems to be for the current iPod touch generation, judging from the headphone jack opening at the bottom. We will soon find out all about the Sprint Peel as it has already
received the FCC's nod of approval.
