hello everyone
i have a 3310 and a 3330 that i would like to unlock i have used a data cable that i recently bought which is supposed to be f and m bus i have used the software nokia tool v3.03 but all it says when i try to read the phone, is phone not connected or f bus error i have used the same cable but with different conector to unlock a 3210 which worked ok can anyone help please i am not into unlocking in a big way so i am only a beginner
i have heard some phones need to be flashed is there a way of finding out which ones

i know this was long but THX anyway

connect cable
turn phone on
read phone
clear sp locks

that should work, are there any errors you are seeing on the phone or computer?
