Shaking up the nascent market for electronic books for the second time in two months, Amazon.com will begin selling e-books for reading on Apple’s popular iPhone and iPod Touch.
Starting Wednesday, owners of these Apple devices can download a free application, Kindle for iPhone and iPod Touch, from Apple’s App Store. The software will give them full access to the 240,000 e-books for sale on Amazon.com, which include a majority of best sellers.
The move comes a week after Amazon started shipping the updated version of its Kindle reading device. It signals that the company may be more interested in becoming the pre-eminent retailer of e-books than in being the top manufacturer of reading devices.
