    Ok, so how exactly am I supposed to unlock my 3GS running iOS4 without being able to Jailbreak it first?? I followed the link you provided, but the current version of redsn0w is NOT capable of Jailbreaking iOS4. I tried. Didn’t work.

    Suggestions??

      You need to wait for the Dev team to update Redsn0w for windows users. Hopefully it will happen in the next few days

          No it isn’t working fine at all.

          It says “Unable to recognize specified IPSW.”

    it should work fine with 3GS. did you guys update to the new iOS4? i did on my 3G first, then jailbroke it.

    the location for the ipsw for windows 7/vista is:
    C:\Users\Your User Name Here\AppData\Roaming\Apple Computer\iTunes\iPod Software Updates

    for mac:
    ~username/Library/iTunes/iPod Software Updates/

    i did it yesterday with my 3G, though i cannot confirm it works with 3GS, it worked flawlessly with my 3G, AND even got to unlock. anyone looking to buy a white 16GB 3G unlocked and jailbroken? lol

    Hi! After running redsn0w and ultrasn0w my iPhone is running very slow. In addition it doesnt look like the unlocking worked. I followed the directions- first running redsn0w then ultrasn0w. My version is OS4.1 on iPhone 3G. Help?!

    Mine too – after jailbreaking my 3G with redsn0w on iOS 4.1, it works fine. Then as soon as I install ultrasn0w, it slows to a crawl. Really – it becomes completely unusable. I have to go back and do the restore via iTunes following redsn0ws directions to even get it back to functionality… I guess I’ll try purplesn0w instead…
