Sooo much information! Thanks to this site and and willerz2 and his Redsn0w "Click this, click that" step by step boot post, (which are impossible to find anywhere else on the web), I learned the jailbreak boot process on my 3gs, since the guy I bought it from Installed 6.1.3, and I just could NOT figure it out. However, now I'd like to learn how to get 5.1.x on it using blobs and APTicket so I'm not tethered-boot anymore. But as I have learned the hard way, Redsn0w isn't exactly self-explanatory to use. (hence the reason for needing step by step mentioned above). So does a "tutorial" like this exist? I can see which blobs I have, but how do I use them? The series of button clicks has me confused. And what about APTicket? I need that too right?
