I have an iPhone 3gS which has been JB. On my Cydia homepage it says that Cydia has SHSH: iOS 4.0,4.0.1,4.0.2 and 4.1 saved. If I were to buy an iPhone4,what are the necessary steps that I have to take to save my SHSH on my Macbook Pro,so that I can JB the iPhone4 that I may buy? I have forgotten the steps I took,when I JB my iPhone 3gS Or do you guys think that it's a waste of time to buy a iPhone4 if my iPhone 3gS is already JB? Please be nice guys...I just don't want to mess anything up! I need to know how to do this step by step! Thanks in advance!
