Not that the jalbreak is out is there any way to downgrade from ios 6.1 to ios 5.1.1 assuming you have shsh?
If you couldnt before you still cant now.
They havent released any programs that will do that yet for A5 devices.
Just a JB has been out for about 2 hours ago.
Give it some time.
Just curious, now that iOS 6 is jailbroken, why would you want to downgrade? iOS 6 is better than 5.1.1 on my 4S in just about every way.
