Hey everyone, so I want to restore my iPhone 4 to 6.1.2 while preserving my baseband and then unthetered jailbreak it. In order to do that, I'm going to create custom IPSW 6.1.2 file using sn0wbreeze and then use evasi0n to jailbreak it. My question is: in sn0wbreeze, should I use the Simple Mode or the Base Band preservation Mode? Any help will be greatly appreciated. EDIT: I used the Simple Mode and then used evasi0n.
