Apple today released iOS 6.1.1 for iPhone 4S users only. This follows reports that a bug in the iOS 6.1 firmware was affecting 3G performance for numerous customers.

Vodafone recently told customers "We’re aware of an issue caused by Apple iPhone 4s handsets that have been upgraded to iOS 6.1 which impacts performance on 3G." The carrier also recommended "that anyone who has not yet installed iOS 6.1 on their iPhone 4s should delay doing so until Apple has confirmed that their problem has been fixed."

How do I downgrade my 4s to the official 5.1.1 ipsw? Most places I've looked said it's not possible but I've seen a few that seem to have done it.

Do you have the shsh blobs for 5.1.1? If you answered no then you cannot. Check out the dev team blog and you will learn some if not all of what you seek to know. I did it with my ipad2 a few months back when 6.0 dropped.
