Back in March, Apple's App Store was blessed with the free Amazon Kindle iPhone application. One of the biggest gripes that we had with it was the inability to purchase new books right from the app itself. While we still did not get that ability, Amazon has done the next best thing: last night they flipped the switch on an iPhone optimized Kindle store.

This freshly optimized store is nice to have but what, if anything, will change when iPhone OS 3.0 is released? If you remember, 3.0 has the ability to make in-app purchases. Will Amazon finally allow in-app purchases and give Apple a 30% cut off the top, or will Amazon stick with the current arrangement to avoid paying Apple for every book that is sold?

So what do you, our readers, think about this one? Either way, it should be interesting!
