iOS 6.1.1 has been released. It's only for the iPhone 4S. If you have a jailbroken iPhone 4S, don't upgrade until evasi0n releases an update that covers it.
And, the evasi0n jail break tool (version number 1.3) has been released that will jail break those iPhone 4Ss running iOS 6.1.1.
Remember - this is ONLY for the iPhone 4S - iPad owners still "only" have iOS 6.1 (which continues to be jail breakable using evasi0n 1.3).
Actually 6.1.2 works great on iPad & iPhone
