A major update was released today for the Kindle for iPhone/iPod/iPad app.

The big news for calibre fans is that the Kindle app can now open .mobi files directly from your iPhone/iPod/iPad mail program and Safari browser. Users can also now transfer .mobi files to their device using iTunes on their computer.

For regular calibre users, this facilitates the transfer of converted files to the iPhone/iPod/iPad without any external programs or jailbreaking.

I plan on changing my calibre options to automatically send downloaded periodicals to my iPhone’s email.
