I am runing a unlocked/jailbroken iphone 2g (original) on firmware 2.2.1 (firmware 04.05.04_G) and want to find out how best to upgrade to the new firmware 3.00 without having to get very technically involved. i think previously I used pwnage/quickpawn tool that was posted on this site. do you have any ideas and will it also remove all my applications that I have downloaded from cydia?
