Amazon.com unveiled its mobile app for Blackberry smart phones today. The app is similar to the iPhone app Amazon launched in December, allowing users to shop, access their Amazon account, and view various editorial features from their phones. The app also features Amazon Remembers, which uploads photos users take of products they’d like to buy and returns listings of similar products available on Amazon. The app works with any Blackberry with a trackball and is available for download from Amazon or for direct download onto a Blackberry.
