One of the best reasons to jailbreak a Kindle is to leverage wireless Calibre sync via KOReader.
Instructions:
from Calibre:
- Click Connect/share
- Start wireless device connection
- Set “Optional fixed port” to 9090 and check off ‘Use a fixed port’
- Confirm
from KOReader:
- Click Settings > Calibre > Wireless Settings
— Check off ‘Enable wireless client’
— Set inbox folder >
/mnt/us/documents— Server address > Add the IP address + port1 of the calibre server (visible in the calibre UI) - Click Settings > Calibre > Connect
At this point, the Calibre UI should change, recognizing the KOReader client.
From there, it is trivial to send books from the Calibre library to KOReader. Select the desired books and then click ‘Send to device’.
Stefan Svartling has a great video tutorial about this.

There’s an “automatic” mode, however it did not work for me. ↩︎
