Hello

I was hoping for some help before I JB my iphone 4.

It's currently running on 4.0.2 and the modem FW is 01.59.00.

I don't mind using either greenpoison of limerain, but I heard I have to upgrade to 4.1 first?

If so, how do I upgrade without upgrading my modem fw? I want to unlock it as well, and heard I need to keep 01.59.00 to unlock ATM.

Thanks for your help.

They have to follow the directions given by Farbod21 though, because they want to be jailbroken & unlocked on 4.1.
