Oh jeez... I'm glad (??) I have the Wifi turned off right now. I'm probably not going to update until I get the new jbpatch version out and verified it to work with a 5.1.0 backend.
That said: has the remote root vulnerability been fixed? (I hope so). Then, @geekmaster, NiLuJe: is the current jailbreak method still working? (Sorry for not being able to investigate this by myself right now... as said, I'll stick with 5.1.0 because I have to get jbpatch straight.)
