Unlock and Jailbreak iPhone 3GS on Windows
Now you can unlock and jailbreak iPhone 3GS running on firmware 3.0 to make it work with any carrier:
Step 1: Now you need to download purplera1n for Windows and you must already have iTunes 8.2 installed.
Step 2: Run the purplera1n app. If you are on Vista, make sure you run it with “Windows XP Compatibility” mode by enabling it from the “Properties” tab.
Step 3: Make sure iTunes 8.2 is running.
Step 4: Click on “make it ra1n”:

Step 5: Let the app do its thing and wait for the phone to automatically reboot.
Step 6: You should now have “Freeze” in the list of applications. Run “Freeze”, download Cydia and let it install it.
Step 7: Finally reboot your iPhone 3GS. Voila! You should now have fully jailbroken and unlocked iPhone 3GS.
Download iTunes 8.2

Hi, Help!!! I download purplera1n and loaded to my iphone 3GS. An image appears but that’s as far as it goes. The image continues to stay on and I can’t turn off my phone. Also iTunes doesn’t recognize my phone either. Please help.
purplera1n doesn’t seem as reputable/credible as redsn0w.
Try googling up how to reboot your iphone.
And then google up “jailbreak iphone 3GS redsn0w’
