Hey guys, so I just restored my iPhone 4 to iOS 6.1.2. I tried to jailbreak with redsn0w, using the 6.0 ipsw, because the 6.1.2 wasn't recognized, and I was recommended to use the 6.0 ipsw. Although my iphone is still thetered, it boots without the need to connect it to my computer. However, Cydia does not work (it closes immediately) and I can't get any service. What should I do? Any help will be greatly appreciated. EDIT: , I unthetered jailbroke my iphone using evasi0n, however, I get NO SERVICE.
