I have restored locked iPhone 4S with ios 5.1.1 . Now I need to activate and jailbreak it. I don't have the original SIM with me. But I can access the settings and Safari browser on the iPhone, and I am also able to browse web pages using wifi connection. I have installed absynthe 2.0.4 on Windows 7 to jailbreak this ios 5.1.1 version, but when I connect iPhone to this system, a message pops up intimating that the iPhone is not activated and the absynthe needs an activated iPhone to jailbreak it. Is there a way I can directly jailbreak my iPhone by accessing internet on iPhone using wifi, without any intervention from my computer.
