Don't forget to secure the device if you install Open SSH, change the default root and mobile passwords from 'alpine' to something...ANYTHING else, via mobile Terminal.
>SU root
>login
>root
>alpine
>passwd
Then enter your new password twice. Rinse and repeat for the mobile account. Patch up the PDF exploit and you should be good to go. You should save your ShSh blobs as well via Cydia or TinyUmbrella. The DevTeam has passed the word that the recursive FW procedure that is accomplished by using an alternate code signing method may not be an option over the horizon due to Apple adapting to the Tools and methods used by the jailbreak community, but it doesn't hurt and may assist you in the short term.
The projected timeframe for Apple to patch i0nics exploit is 5 days, therefore DO NOT update your firmware once jailbroken, especially if you rely on ANY unlock, your baseband WILL get modified if you use iTunes to migrate to official Apple firmware and you WILL LOSE your jailbreak.
More to follow.....
Good luck.
