No you can't, and Apple closed the singing window on 6.1 immediately upon release, meaning there was no warning.
Whilst it is true that there are a number of high profile tweaks which need to be updated, it is already obvious from todays activitiy that these are flowing through quickly.
There is also a bug in the jailbreak (related to the installation of the Weather comoponent) which will be fixed soon via Cydia. A manual fix is already available for h4x0rs
Folks can make up their own mind about what to do, but do NOT assume that blobs will save you when 6.1.1 is released. They certainly can't as things stand.
The launchd exploit is easy to fix by Apple. We just don't know what their appetite is at the moment in terms of blocking the jailbreak as quickly as possible.
But be warned. You are likely to get little or no time to react if 6.1.1 "goes live", so if you are not on 6.1 already you may very well miss the boat.
