No, they didn't, but that doesn't matter. I can live with that notification. What I cannot live with however is the quite annoying fact, that I have to re-enter all my account-data every time I reboot the device. And that facebook & twitter don't update the feed anymore (already deleted fb & twitter-accounts and re-added them. No difference.)

Does flashing (or reinstalling the OS - wait, can I do one thing apart from the other?) mean I have to do that partitioning-thing again? What wouldn't matter, since I have a) the Backup of most files and b) it probably won't take as long, when the partitions are empty.. a bigger problem would be loosing my calendar-entries etc - which are probably not backed up properly, since they are in hidden folders, which ubuntu didn't see. And therefore probably didn't back up.
