Is there really a such thing at the moment for the 3G/3GS? Or all jailbreaks untethered. Because my dad called me and asked me if I would be able to unlock/rejailbreak it, the seller told him that once it reboots you have to redo it. I thought now all the jailbreaks and unlock are untethered since those are, old school phones. He said he won't be able to look at the firmware/baseband for a while, so just asking! Thanks!!!
