The Apple Peel 520 is familiar to all of us now. The device housing a battery, SIM card slot and GSM antenna shrouds a regular iPod Touch much like a protective cover, giving the Touch all the features of a regular iPhone (except the GPS and camera that is).
The 520 would only work on Edge networks, but ZTE have updated the unit with a humped back design and faster 3G connection.
3G Apple Peels will be available in the U.S later this year on Sprint, but there are currently no plans for a China launch.
