I've acquired a 3GS iphone with ios 6.0.1 already put on by previous owner, its never been jailbroke and no blobs ever saved, so I know I can't go back to ios 5xx. I'm not clear about whether I can JB tethered even though its too late now to save any blobs. Its got bootrom 359.3.2 and is factory unlocked if that makes a difference. Also if it is possible, by which method should I use, sn0breeze or redsn0w? And, if a an untethered JB is then released for say, ios 6.1 in the future will it be straightforward to update and do an untethered JB? Oh, and when ios 6.1 comes out will there be short window when I can save blobs or has that option gone forever for this phone now? So much to learn, thank you for any advice.
