Hello, I have a 3gs 4.3.1 BB 4.26, I upgraded to firmware to 5.01 using latest redsn0w, maintaining BB 4.26. When I try to do the second stage (just boot) to install cydia I get this message The IPSW for the following build is needed:
iPhone2,1_5.0.1_9A404

The required IPSW is either not public or not
available right now. Please provide it
manually using "Extras->Select IPSW".

I don't have this IPSW, please help, what do I do now?

Question, if my 3gs is already JB on 4.0, can I just build the custom IPSW 4.1 and restore to it without re JBing

I have an un activated 3gs, is there a way access itunes and get the files without activating the phone?
