If you own an iPhone you are most likely familiar with the jailbreak concept, but for those of you who don’t already know I will try to present a brief explanation. Therefore jailbreaking is the simple procedure which grants you full access to your device. You can jailbreak the following devices: iPhone 2G, iPhone 3G, iPhone 3GS, iPhone 4, iPad 1, iPad 2, iPod Touch, iPod Touch 3G, iPod Touch 4G. In order to jailbreak iPhone 4 running on iOS 4 4.3 you will have to use one of the following jailbreaking tools: Redsnow, Snowbreeze, Pwnage Tool and GreenPoison.
