    Okay so about 3 hrs after came out I jailbroke my iPhone on 4.0.1. Now I need to restore to non-jailbroken firmware due to warranty work from apple. I was wondering, how do I update to 4.1 when I have a jailbroken iPhone? Can I do it directly through iTunes or do I have to do it some other way like sauriks signature server? If I can do it through iTunes, can I back it up or will it like brick the iPhone or something? I also don't want to have the jailbreak detectable. I have heard that apple has added some watermark into the new 4.1 firmware so that people cannot bring it back to apple after a restore without apple knowing.
