Amazon Kindle for iPhone, iPad gets big 2.5 update
Amazon today posted a major update to the Kindle app for the iPad and iPhone (free, App Store). Its 2.5 update now takes advantage of iOS 4 and will finish, though not start, a book download in the background. Borrowing from its companion app Stanza, it now supports raw files as well and can load supported text from Mail or Safari in addition to using iTunes' File Sharing for sideloading books from a computer.
The update now encourages more adoption of free books and has access to Project Gutenberg's collection of "millions" of public domain books. Minor changes bring better image zooming and a new book indicator as well as multiple unspecified bug fixes.
Amazon hasn't said when it expects the updates to reach Android, Windows Phone 7 or other platforms that carry its mobile app.
