Use the phone's camera to get product information.
The new app is appropriately named "Shopper." Take a picture of the item you're interested in (with your phone's camera, of course) and Shopper will bring up product info for you.
So far, the app recognizes most CDs, DVDs, video games and book cover art. It can also recognize most barcodes.
The app also includes a Voice search feature in case you're curious about something you can't immediately take a picture of.
You can star items that will be collected into a shopping list for you.
