Hey guys, sorry if this is redundant but I have done my homework and researched this extensively but to no official answer. I have an iPhone 3GS running 4.2.1 and I wish to jailbreak it. Now I have been reading and reading about this apparent untethered jailbreak that geohot has in the works but not released yet. And I know that a redsn0w one exists but is still in testing for bugs and is also tethered. But it just hit me that these may just be for A4 devices like iPhone 4 and iPad, and that my 3GS may be an exception?? Any chance that I am right and am just somehow missing this is my google searching? Thanks guys.
