upgrade to pr1.2 via apt stopped almost immediately b/c too little space in root (obiviously).
since i was too lazy to look up the way to point apt to another location. it was rather late, and after seeing the inept way, nokia handles package creation and management, i used the little blinking symbol.

but ususally, if you know your way around debian, apt and dpkg, no situation is unsolvable.

anyway, flashing is certainly the fastest and most painfree way.
