    I'm on a carrier that needs the phone to be unlocked but i found out that my bootloader is 05.09. Can I downgrade the bootloader or should i upgrade back to iOS4?

    If you are on 3.1.3, jailbreak with Spirit, and unlock with Ultrasn0w. Bootloader doesn't have any effects on unlocking at this point.

    Just out of curiosity, wouldn't Pwnage or Redsn0w for JB be easier if on a 3G? Then ultrasn0w. I only say that because that is what I have (3G) and from what I read there have been problems with spirit. Just wondering is all :)

    Did you add and install Ultrasn0w in Cydia? Redsn0w doesn't unlock.

    You didnt do something right.
    What kind of iphone are you using and on what firmware?
    You have to tell us that first before any other question.
    Bootloader doesnt say much.

    Update again to official 4.0 and then use redsnow to jb and ultrasnow thru Cydia to unlock.

    Yes 3G models will be slow with 4.0 especially if u enabled multitasking thru redsnow then forget it:)
    Not sure what u did but try a restore again and rejb and unlock again. Unless there's something wrong with your sim.
