Ummm...a mix-up here somewhere I believe.
I am referring to the desktop app, not any kind of firmware.
Ok, downloaded the installer file at the kobobooks and it returned me to version 1.6.
So it hasn't been updated, and I'm still not going to upload the installer...sorry.
I'm sure it's coming...and as Zoran sort of points out there may be functionality that is dependent on what's coming in the next firmware, so having the updated app might not be the best move anyway.
The current firmware for 1st Gen Kobos is Ver 1.4 but an update is expected any day now.
I'm not even gonna say what version the software on the Kobo WiFi unit itself is 'cause that will only muddy the water.
