Hey everyone, I recently purchased a 4S and have been pretty bummed that I can't downgrade the iOS without having saved SHSH files... When I try to search on this forum for ways to downgrade without the SHSH files, I just find a bunch of "it's not possible" like posts, which aren't really helpful. Could someone give a better explanation as to why the jailbreaking community hasn't been able to facilitate this? Thanks. Edit: I'd even be down with a tethered downgrade, is this possible?
