I just recently purchased an Iphone 4. I want to downgrade the iOS6 to any "jail-breakable" iOS5 version. After doing some research, I understand that I must first have a saved SHSH Blops file on my phone. Unfortunately apple has stopped "signing" for these Blops files? Where do I go from here? Can I get a ios5, or do i have to wait for a "un-tethered" version of ios6 to be released?
