Amazon has launched version 2.5 of its Kindle app for iOS with a few key new features. First, if you’re running iOS 4 you can now download books in the background while running other tasks. You still need to start your download from the Kindle Store, and to be honest, most eBook files are so small that they’re done downloading before you know it, but this is still a good feature to have for times when your internet connection slows to a crawl.
Kindle 2.5 also adds support for free, copyright-expired books from Project Gutenberg, the Internet Archive, and other sources. Just visit the web site, click the download button for the Kindle version, and on your iPhone, iPod touch, or iPad, select “Open with Kindle.” You can also use the File Sharing option in iTunes to transfer files from your computer.
Amazon has also made some bug fixes and improved image zooming.
The Amazon Kindle app for iOS is available as a free download from the App Store.
