Cannot unlock Iphone 3gs 4.0.1 already jailbreaked....Help!

[Carlanga]

can he update it to 4.1 when apple isn't signing that anymore?...

Yes, I did it today for a friend that wanted 4.1 on his 3GS and keep his older 4.01 BB, I used PT then the PT DFU then option restore on iTunes to install the custom fw I cooked and worked no prob. 🙂 He has all the hashes, but I have never changed the server in my macbook so apple must still be signing 4.1!

yep, surprisingly apple is still signing that fw.
