Even though we have always been against Jailbreaking the iPhones, we took the plunge the other day after many frustrating hours with the iPhone 3G and IOS 4, and surprisingly enough the phone actually works much better now, which is why we have decided to add this How To Guide…..
Remember that this is not supported by Apple, and that if anything goes wrong they will not help you, and WE are not responsible for any bricked iPhones either.
