Unfortunately, no. Neither can you use the wifi to fetch epub books off the internet, e.g., Feedbooks, Gutenberg, etc. Everything is off limits. Sony has locked the device down. You may only download content through the ever-watchful-eye of the Sony eBook Store.
I/we can only hope and pray that down the road some of the community's talented Devs find a workaround.
