Im using mac os x, and i have an iphone 3g 16gb running on firmware 2.2.1, with that said i followed all the instructions to using quickpwn to jailbreak from the iphone 101 page on this site, but right after i complete the series of holding and letting go of the power and home screen button, it gets to the progress screen and continues to be stuck there, the "loading" circle spins but the progress bar does not load at all, its like the progress is just completly frozen, i left it like that for about 30min and still no progress. Is there a step i am missing that is causing this? I have both files downloaded also, the quickpwn app and the firmware zip file.
