    You need shsh blogs stored in Cydia or stored locally.
    Assuming you have 4.0 shsh blogs with Cydia.
    PC : Vista/win7 : Run Notepad as Admin and open up your hosts file and add this line
    74.208.10.249 gs.apple.com save it and reboot
    Put your iphone into DFU mode
    Do the Shift + Restore to 4.0
    Error 1015 pops up, Use Tiny Umbrella to kick it out
    Now at Emergency Screen.
    Run Redsn0w 0.9.5b5-5 and point to 4.0 ipsw
    You are set on jailbreaking but not unlock.
