    guys, i have an iphone 3g and it has been jailbroken using quickpwn on windows so i know what i am doing. my cuzin bought an unlocked iphone 3g in hong kong and bought the new macbook air with ssd. i tried to jailbreak his iphone using pwnage and quickpwn for mac but to no success using his air. i have created the custom firmware but when i tried to restore it with the iphone 3g it just says error 21. i tried searching the net for that error and tested everything that was suggested still did not work. like creating a dir using terminal. can you guys help me? is it possible that the new macbook would not allow jailbreaking?

    Did you enter DFU correctly?

    Hold down the home and power button for 10 seconds.
    Let go of the power button while holding the home button.
    In about 20-30 seconds iTunes will recognize it and you can restore.
