Fixing something which aint broken.

There is always a risk doing big upgrades in IT-systems.
And I need my N900 to work these next days. If something goes wrong in the upgrade, I wouldn't have time to concentrate solving the problems. Also the extra applications has to be re-installed.

Is it a big or small risk, I do not know or much care. I just know I am wise not to take it currently. I've learned my lessons with IT-systems before.
