I have a Droid Razr but I need some assistance. The phone has the Kindle App which I have no problem with so long as the book was directly from Amazon. The problem I have is that I get most of my books from other book sites and would love to be able to read read them on my phone. When I email the book to myself to download it to the phone, the attached book has the message "Unsupported file type" and I am not able to download the book at all.
Does anyone have any information about this and how I can get MOBI books loaded onto the phone? I have convertrd the format to PDF in Calibre and can download those and then I put them into the Kindle folder. I can then open them using the Kindle App. But in the Kindle app you don't have any of the options you would have if the book were bought from Amazon.
Does anyone else have this problem or know of a way around this? Thanks much for any advice
