I have a 3gs, old bootrom. The device was jailbroken and unlocked. Just used redsn0w to upgrade from 4.0 to 5.0.1. Preserved the 04.26.08 baseband. When I try to use redsn0w to jailbreak and install cydia I get the following 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." The redsn0w version is 0.9.9b9d. So at this point, I still have an unlockable baseband, but no cydia and no jailbreak. Any help will be appreciated.
