And now Sprint is apparently looking to piggyback one of these devices on Apple's iPod touch. Macrumors reports on new filings to the FCC that show a device that's almost a case; it's designed to be attached to the back of Apple's handheld, providing local Wi-Fi service anywhere you happen to be. It's called The Peel, and it doesn't connect to the iPod touch at all except physically -- it's just a case that wraps around and sets up a Wi-Fi spot whenever it's hooked up.
It's worth nothing that this isn't the first time Sprint has tried to pair up their 4G service with an Apple device -- you might remember the iPad 4G case that came out a while back. Makes a lot of sense -- Apple's devices need a connection, and Sprint has a much better chance of making you get one if you've already got a device to use it with. We'll keep an eye out for an official release of The Peel.
