It may be duking it out with Apple over rights to the "app store" name, but Internet retail giant Amazon has, nevertheless, optimized its flagship MP3 store specifically for the Cupertino company's iPhone and iPod devices. Amazon's browser-based Amazon MP3 Store has been optimized for Safari on the iPhone and iPod touch to cleverly side-step native iOS app restrictions and its 30 percent fee structure for in-app purchases. "Since the launch of the Amazon Cloud Player app for iPhone and iPod Touch, a top request from customers has been the ability to buy music from Amazon right from their devices," said Steve Boom, vice president of Amazon Music in a press release .. "For the first time ever, iOS users have a way do that-now they can access Amazon's huge catalog of music, features like personalized recommendations....They can buy their music once and use it everywhere."
