QuickPwn 1.0 for Mac released by Dev Team. Previously this was only available for Windows users supporting firmware version 2.0.2. This QuickPwn for Mac as a reminder works only on 2.0.2 firmware version of your iPhone and iPod Touch.

More for dev team blog.

QuickPwn is not a replacement for PwnageTool, they are different tools and provide different features, QuickPwn is for quickly pwning a device, whereas PwnageTool is designed to custom build and tailor the ipsw production process, both tools will be actively developed in the future.

To use QuickPwn 1.0 Mac OS X your device should be running 2.0.2, if it isn’t then you can upgrade it to 2.0.2 using iTunes and then use the QuickPwn tool, we repeat, it’ll only work on version 2.0.2 of the iPhone or iPod touch firmware.

Use at your own risk. And please note that this does not unlock iPhone 3G version.
