I successfully installed 4.2.1 on my 3GS while keeping my baseband at 5.13.04 using the Dev team's instructions here. How do I now jailbreak and unlock my 3GS keeping my baseband? EDIT: When I point redsn0w to the custom firmware that pwnage tool created for 4.2.1 it doesn't recognize it. Should I point redsn0w to the original 4.2.1 firmware? Thanks in advance and happy holidays!
