: Gear4 has introduced the IceBox X-Clip Series, a new line of interchangeable accessories designed for Apple’s iPod nano. The line starts at $22. The first two IceBox C-Clip devices are a clear hard plastic case for the iPod nano, equipped with a belt clip attachment, retailing for $22, and the IceBox C-Clip Splitter, which combines the belt clip attachment and a headphone jack splitter, for $29. Gear4 plans in short order to expand the X-Clip line to include other accessories. Also included with the current devices are a two-piece protective film to keep the iPod nano from getting scratched and a lanyard.
