Ok so I have been out of the 3G jailbreak scene ever since I got my 4, and my 3G stayed on 3.1.3. My friend gave me his and wanted me to jailbreak it but it is on 4.1 old boot room model. MB. Last I knew it was able to be jailbroken but only if it was previously jailbroken on 3.1.3. Can I jailbreak with something like sn0wbreeze or redsn0w even though it has never been jailbroken before?
