Hi! I don't remember what software I used to jailbreak my iPhone 4s. I jailbreak it long time ago the moment they released it. I jailbreak it on version 5.0, but it's getting out of date and I don't even have 4G network. So what is the latest version I can upgrade and still jailbreak on my iPhone 4s? Can I have links, instruction, etc? Thanks! P.S. What about iPad2? I wish to jailbreak that too to get Cydia. Thanks!
