Zune HD, or opt for Insignia's NS-HD01. As of today, Gigaware is changing all that, and it's hoping to give HD Radio a kick in the pants by opening it up to every single iPod touch and iPhone user in the US. iBiquity's own HD Radio module has been tucked neatly inside the clickwheel in-line adapter you see above, giving any iPhone / iPod touch with iPhone OS 3.0 (or greater) the ability to listen to HD Radio and FM stations in their area. The (now available) adapter itself sells for $79.99 exclusively at RadioShack, while the accompanying app -- which sports a manual tune wheel or auto-seek option, social network integration, bookmarks and iTunes Tagging -- is available to download free of charge. It's a novel idea, sure, but something tells us the limited availability and lofty price tag will keep it from selling like gangbusters.
