Dekortage writes: Amazon's e-books aren't just for the Kindle anymore: they will be supporting Apple's iPhone and iPod Touch as well. Available today, Amazon now offers Kindle for iPhone (note: App Store link) for free. Among other features, existing Kindle customers can access previously purchased e-books on all of their devices at no additional cost, and synchronize bookmarks back to Amazon's servers so they can pick up where they left off, regardless of device. However, it only supports books, not magazines or newspapers. An early review from CNET suggest one advantage of the iPhone over Kindle: comic e-books in color.
