Hi MakeUseOf! I would just like to ask for reliable websites which allow me to download jailbreak software for my iPhone 3G with iOS 4.1 for free. I really need to update my iOS version so I can install an antivirus on my phone. Thanks!
RedmondPie site is good and reputed one -
This is free http://iphone.pandaapp.com/jailbreak/ tried and tested app ;)
check iclarified.com which is a great website for jailbreaking and iphone tutorials.
