errr i own a nokia 6260 got some probs like pressing the "C" button for a few times will cause an error called App. Closed MCE and now my Themes folder in my menu has problems. If i select it it will show an error message App. Closed PSLN.. someone suggested i updated my firmware.

after seeing this post i am rather confused.. what is "flashing"? and could someone explain to me what firmware is really about? really a newbie here XD
