Amazon has confirmed that their Kindle for Android ereader app will be released this summer, offering Android device users the chance to not only read existing titles on their smartphones but to buy them and download them direct to the handset. The new app will also use Amazon's WhisperNet technology to synchronize all copies of the ebook - whether on a dedicated Kindle, or being read on another Kindle app - up to the last-read point.
Amazon currently offer versions of the Kindle app for the iPhone, iPod touch, iPad and BlackBerry, together with Mac and PC versions. However not all are integrated with the retailer's ebook store for on-device purchases. The app itself will be a free download; you can sign up for status updates on its release here.
