I hessitate to ask a daft question, but as I am not confident I know how to proceed, is the idea to re-install v3.0? - I got an 'unlocked' IPhone today only to find it's not. I have downloaded Redsn0w and found 3.0 IPSW. - A little more text on how to link the 2 together would be really appreciated.
Thanks in anticipation
