If iBrickr doesn't work on 1.1.1, try locate the Services.plist file in /System/Library/Lockdown, and check if it has an afc2 section, it must be there to make iBrickr work with 1.1.1.
The full section looks like this:
<key>com.apple.afc2</key>
<dict>
<key>Label</key>
<string>com.apple.afc2</string>
<key>ProgramArguments</key>
<array>
<string>/usr/libexec/afcd</string>
<string>–lockdown</string>
<string>-d</string>
<string>/</string>
</array>
</dict>
Note:
1. the iPHUC defaults to using com.apple.afc, to force it using afc2, enter the following command in iPHUC:
setafc com.apple.afc2
2. an alternate method is to directly modify the com.apple.afc key, however, this may (or may not) affect the normal system operation. To keep things easier, create an afc2 section is recommended.
