Amazon’s online MP3 store has now been optimized for iPhone and iPod touch users thanks to a HTML5 redesign. That means, for the first time you’ll now be able to buy music from Amazon using your iOS device. It’s important to note, this is not a new app in the App Store, you need to access it using mobile Safari. Once you’ve accessed it, you can purchase songs and albums, then use the Amazon Cloud Player app for iPhone to stream them. The web app promises a great experience complete with recommendations, user ratings and discounted albums.
