I said it once for iPod, I'll say it again for the Sidekick3... Keep your Sidekick handy AND protected with this ultra-futuristic Boblbee Aniara. I have the black one, and it is the perfect size for a Sidekick3.

It's designed to be attached to the shoulder strap of a backpack, especially any of the Boblbee backpacks, including this amazing Boblbee Scorpio Backpack.
