I have a 3GS which I updated to 5.0.1 jailbroken last night, it was originally bought on a PAYG O2 deal and I unlocked and moved over to Orange, every time I upgrade OS I have to go through the pain of getting a hacktivated ipsw file or unlock then ultrasnow etc.

I have the original O2 sim which I have to use in itunes sometimes to activate the phone but how easy is it to unlock via their website and still use on Orange, I know I probably need the original sim in it but can I make then request then a week later pop the O2 sim in, let it unlock then swop it back?

Yeah its fine, I done the same with my 3GS (Sold as unlocked a while back)

Just connect the phone to Itunes once you get the text message to confirm the unlock.

Sorry to hijack, but if you have an unlocked (by O2 or any other carrier) it is not permanently unlocked?
My missus has a 3gs which has been unlocked by O2, she will be upgrading to a 4s and I was gonna take the 3gs off her hands and jailbreak it.
It is currently on 4.3.3.
If I upgrade it to 5.0.1 it will be locked again?
