Version 2.0 of Amazon's Kindle for Android software has snuck out tonight, bringing with it access to the company's library of newspapers and magazines, the ability to purchase content in-app, and the freedom to choose where you want to store the app itself, which is now happy to reside on your microSD card. Other additions include social networking updates of your reading progress, the appearance of chapter titles in the reader status bar, zoom for images and graphics, and the volume keys doubling up as your page turners should you wish them to do so. The updated app's available in the Market now -- you know what to do with that QR code, right?
