Belkin has introduced pink versions of its iPod nano cases, the Sport Armband and Remix Metal. Available from BestBuy the iPod nano cases each cost $30 (around £16); they went on sale on Sunday. A portion of the proceeds go to a breast cancer charity.

Belkin will donate 10 percent of the retail price of each iPod nano case sold to support Susan G Komen for the Cure, a non-profit organisation focused on finding a cure breast cancer. Belkin has pledged a minimum of $100,000.

The iPod nano Sport Armband is affixed with pink accents and a pink ribbon (the official colour for breast cancer awareness). The iPod nano armband features a stitchless construction and it's hand-washable and water-resistant. The Remix Metal case for the iPod nano is made of clear acrylic and brushed metal. It also sports a pink finish and pink ribbon graphic, and uses a soft-touch clickwheel protector.
