Google Product Search for mobile for iPhone and Android-powered devices lets mobile users search for products on the go to get quick access to product information. To try, just go to Google.com in your browser, and try out Google Product Search for mobile. If you've already submitted items to Google Product Search, you don't have to do anything extra to get your product information to show up on Google Product Search for mobile. If your items are not yet listed in Product Search, it's easy: just submit your product information using this guide and keep submitting frequently to keep your listings up to date. The new Product Search results pages for mobile are available in the US and UK, and for iPhone and Android-powered devices.
