As far as the Kobo Touch is concerned, the new firmware seemes to be not yet rolled out in Germany. I had to do a factory reset yesterday (once more ...), and what I got via the Kobo Desktop was Version 3.01 again.
Well, I'm not very keen on getting the new firmware installed; its advantages appear to be quite neglectable in realtion to the Touch, and - above all - I wouldn't like to get "my" - Sergey's - Launcher to become corrupted.
But it were an option, if there were any notification if the "not recognized nSD card issue" should be amended by the new firmware. In fact, firmware 3.0.1 runs pretty stable on my Touch (thanks to the developers so far!), but the nSD card will not be recognized at booting the shut-down reader - never. That's annoying.
