I have a factory unlocked iphone4. Now I want to jailbreak it finally I got lot of threads discussing about the same; but got confused. Some forum say that my baseband should be 4.10.1 to jailbreak. My phone Software is 5.1.1 and Baseband 4.12.1; can I use RedSn0w to jailbreak my iphone. Thanks and sorry if it is duplicate thread; in that case you can give me a pointer to the other thread.
