Master Lock has introduced its new iCage Locking Skins for the fifth-generation iPod, iPod classic, and second- and third-generation iPod nano. Each iCage includes three full body thermoplastic iWraps for scratch protection, a metal sled to hold the iPod, a three-digit combination lock, and a cable. Users are expected to secure the iPod inside the sled and then wrap the cable around a fixed object and back onto the lock. Master Lock’s iCage for fifth-generation iPod and iPod classic will sell for $20, while the second- and third-generation iPod nano model will sell for $15. All of iCage models are expected to be available later this month.
