Iphone 4s want to restore to day one and stay jailbroken
I have a gsm iphone 4s 16gb that is on 5.0.1 and is jailbroken. I have straight talk service and have been having service issues. I want to restore to a jailbreakable firmware and then rejailbreak. I intend to then go with at&t because I want trouble free service and need the reliability for my job. cydia and tiny umbrella have 5.0.1, 5.1, 5.1.1 and 6.0.1 blobs on file, but I cannot seem to restore to 5.0.1, or 5.1.1 with itunes. I cannot do it with redsn0w I get the apticket failed because my phone was originally 5.0.1
do I have any options?
