Sure, Amazon could pit the Kindle squarely against phone- and PDA-based e-book apps, but why not play both sides? The company had previously mentioned its desire to embrace non-Kindle devices in its digital delivery ecosystem, and the first fruits of that labor have now hit the iPhone App Store. The uncreatively-named Kindle for iPhone allows you access to all of your Kindle content right from the comfort of your iPhone or iPod touch, and if you have the good fortune of owning an honest-to-goodness Kindle, Whispersync will kick in to keep your location synchronized between readers. It's a huge win
