Replace the logo.png and the recovery.png files in the quickpwn directory with your own custom bootloader images. You can download the iClarified boot logo here and the recovery logo here.
If you are creating your own remember the rules are very strict. They must be RGB or Grayscale format with Alpha channel and dimension bellow 320x480.
Connect your iPhone to the computer via USB cable, make sure iTunes detects it, and then close any iTunes processes that start. Then in the quickpwn folder double click either iPhone 2G.bat , iPod touch.bat , or iPhone 3g.bat depending on which device you are using.
If prompted click the Run button to launch the batch file.
You will then be asked to power off your iPhone and press Enter once it has been turned off.
QuickPwn will now help you put your iPhone in DFU Mode. Read through the instructions so you know whats ahead then type in y and press Enter. As an alternative you can put the iPhone into DFU mode yourself using these directions then press Enter.
First you will be asked to hold down the Power button for 5 seconds. Then you will have to also hold down the Home button for 10 seconds without letting go of the Power button. At the end of 10 seconds you will need to release only the Power button.
After a few seconds of holding down just the Home button QuickPwn will detect the DFU mode and start performing operations.
After 8 operations are performed QuickPwn will ask you to "Please wait while your iPhone is Jailbroken". You can press any key to close the command prompt window.
Your iPhone will display a turning wheel and in a few minutes will be jailbroken! If you have a 2G iPhone and would like to unlock simply install and run BootNeuter from Cydia.
