Much as we admired the potential of the YotaPhone in our recent review, we just couldn't overlook its lack of support for popular e-reading platforms like Amazon Kindle and Google Books. That problem hasn't been solved just yet, but things are starting to move in the right direction: the dual-display handset has now been made to work with an alternative (and relatively popular) e-reading app called FBReader. This app will let you display and swipe through Word and .rtf documents on the E Ink panel, as well as unencrypted .epub and .mobi e-book formats of the sort that are traded in smaller e-book stores and some shadier, copyright-dodging parts of the web. PDF files should also be supported by the next version of FBReader, which is currently in beta. Meanwhile, Yota Devices tells us that it's "discussing potential collaboration" with Amazon in order to bring about Kindle support, which, if it happens, would be nothing short of a breakthrough.
