Recently released FCC documents reveal that Sprint is set to launch what appears to be a new case for the iPod touch that would enable 3G networking on the WiFi-only device. Manufactured by ZTE and called the "Peel," the case is essentially a MiFi-like mobile hotspot that snaps on to an iPod touch, giving it a network connection wherever you can get a Sprint 3G signal.

The Peel has its own 3.4Whr lithium ion battery, which is good for about 40hrs of standby time—there's no mention of how long it would last in active use, but our guess is perhaps a few hours. In addition to giving 3G network access to an iPod touch, it can also connect other WiFi devices. It doesn't appear to have a limit to the number of simultaneously connected devices (the manual submitted to the FCC suggests this number is configurable), unlike most mobile hotspots that usually limit connections to four or five. Phone Scoop also notes that the device is only cleared to operate on the slower EV-DO Rev 0 standard, and not the faster Rev A that most current 3G devices use.

We're not exactly sure what to think of the Peel (Apple, Peel, get it?). It seems that if an iPhone really appealed to you, you wouldn't have opted for the iPod touch to begin with. Then again, there are some users who would rather have an iPhone with data but no voice, and on a different network. Depending on the pricing and data options—especially if there is a pay-as-you-go option—it might be a nice complement to an iPod touch. The added utility of being able to connect multiple devices—one clear advantage over an iPhone—is offset somewhat by the slower 3G speeds.

Sprint tried to attract Apple device users with a similar tack when the WiFi-only iPad was released, offering users a free iPad case with a pocket that would fit the carrier's 4G/3G Overdrive mobile hotspot. Still, we're wondering if there are any iPod touch owners out there excited by this news. If you are, let us know in the comments.
