Addendum: If you mean the initial factory version (prerequisite for the jailbreak procedure) you're still running on: Well, it's not recommendable from my point of view to use this for "productive" use. Update to 5.8.7(.0.1) will be the probably most secure way, as you then have the option to redo the jb procedure via downgrading to the initial factory version. Just to be sure...
