GizMac Accessories has begun taking pre-orders for its Titan Clear iPod case, and said it is expanding its line of polycarbonate iPod cases for Apple's second-generation iPod nano. The cases are designed to protect the portable player from scratches and other minor damage while providing four ways to carry the iPod. Titan cases come with a thin film material to protect the clickwheel from damage, and each case features a belt clip with a 360-degree rotation and lanyard accessories to accommodate a wide range of ways to wear the portable device. Titan cases for Apple's second-generation iPod nano cater to charging cables as well as oversized earphone jacks, and are available for pre-order at $25 each. The cases are slated for shipment in the last half of February, according to GizMac.
