I think that people are having problems because the soft update does not work properly on 1.1.1 iPhones. Find tutorials on how to go from 1.1.1 to 1.1.2(not really hard) AND THEN do the iBrickr 1.1.3 jailbreak/update. Every single thing works on my iPhone and everything that was on 1.1.2 stayed intact. 3rd party apps of course got wiped but no big deal just reeinstall them.
Just wanted to point it out. If you guys already knew this, just ignore the thread.
