Thanks to Anna for pointing out this article in the Bookseller. It reports that in the USA it is now possible to download a free Kindle App for iPhone and iPod Touch devices, so that Kindle users can choose to read or transfer their digital books to the device, and even buy Kindle formatted books directly from Amazon. However, it is not available to UK iPhone users at present, so I have no excuse to get myself an iPhone just yet!
