I wouldn't trust the info on
www.pocketbookreader.com anyways (not even sure how official the site is, but it looks like its not).
For example about the 602/902 they say:
"BlueTooth
Connect Bluetooth supporting devices, such as headphones, keyboard, cell phones (for Internet connection and file transfer), and PCs etc., to PocketBook Pro ..."
Which we know isn't accurate at all.
