I jailedfree and unlocked my 1.1.1 iPhone like a month ago using http://iphone.unlock.no/ tutorial. Everything worked like a charm. Until today, that I wanted to use some iBrickr features, but that required v1.0.2, so I downgraded and iBrickr tells me that Its jailfreed, but its not cause if getting the "world Activation Screen"... but, it looks like part of it work since i can install apps and upload files using iBrickr, I even installed anySim, and I can navigate its file system. What am I missing?

p.s. Im still gettting 04.01.13_G on the phone.
