I googled some,
http://www.amazon.com/GENITOPE-INITI.../dp/B000F3UGMY
"includes free wireless delivery via Amazon Whispernet" "Available for download now."
Other intresting quotes
"Auto-delivered wirelessly to Kindle via Amazon Whispernet." Auto-deliverd? Can you only buy from the kindle then? Sounds a bit stupid... But if it is free it would prob be allright.
And notice that the book is in HTML format...
