Hi, I have an iphone 3GS 3.1.2 I it was jailbroken with Spirit to 3.1.3 firmware and now I would like to update it to 4.1 firmware but don't know how to do that:/ Can I update my iphone without using itunes? I am running on Windows Vista. Also my husband has an ipod touch 3rd gen and it's jailbroken with spirit also to 3.1.3...is it the same for that too? I would also like to rejailbreak both after updating. Please someone help me??!
