For all my e-reader Bibles go to my Bibles for e-readers page.

I have formated the   Russian Synodal Bible for Kindle with Cyrillic letters.   Parrallel I have formated the Greek NT WH with accent marks.   Both are laid out similar to my KJV format for Kindle.  They are saved in .mobi format so they may work on some other devices as well.   Let me know if you find these useful.

UPDATED: Navigation upgraded. ePub format made available. Go to here for the latest.

NOTICE:  Works for Kindle 3. For Kindle 2, the kindle needs to be jail broken and the Unicode font hack applied, which can be found here  http://blogkindle.com/unicode-fonts-hack/ .   I have successfully used this hack, but use it at your own risk.
