Now, iPod docking stations support charging capability for iPhone 3G, thanks to Scosche's converter called passPORT Home Dock. It allows users to charge their iPhone 3G on the iPod docking stations.

The passPORT Home Dock passes through audio, video, and data functionality to the iPod docks, making it fully compatible with the older iPod docking stations. Keep in mind this convertor is not a stand-alone dock and does not add audio/video functions by itself.

According to the 's Scoschesite, the passPORT is specifically designed to fix the charging error associated with several iPod docking stations.

Bundled with the dock adapter for Bose SoundDock I, it is available now from Scosche.com and Amazon.com for $39.99. It will be available also at Walmart in May.
