How to Jailbreak iPhone 3G on iOS 4.1 using PwnageTool ( PC / MAC )

In the following guide you will learn how to jailbreak the iPhone 3G, running on pure iOS 4.1 power. Although other guides have been released, using different software applications, this one here is known to work the best. PwnageTool does the job perfect, by giving you full access to Cydia apps and also, hacktivating your iPhone 3G. By jailbreaking the iPhone 3G on iOS 4.1, with PwnageTool, you can also unlock it using Ultrasn0w, because this tool preserves the baseband. We will write a guide for that later today, so stay tuned.

Before you start, please note that this guide is only available for the iPhone 3G, with old bootroms, which has at least been jailbroken once with either redsn0w, PwnageTool, Blackra1n or Sn0wbreeze. If you used Spirit or JailbreakME, stay away. For those who own an iPhone 3GS, use this guide instead.

Update: PC guide here.
