Edit: It looks like this may be fixed in latest blackra1n. I have not tested this personally but have been told it is the case. Finally.
Just a warning about blackra1n. Geohot released blackra1n a couple weeks ago, and it was pretty good. Unfortunately, Geohot has included a very buggy version of Icy which, when installed, will pretty much screw up your whole jailbreak causing you to have to restore.
Shame on Geohot for not fixing this. We have told him numerous times there are issues. Users have messaged him, he has been notified, he just doesnt care. Anyways:
–> Do NOT install Icy in Blackra1n <–
The icy bundle is broken and does not have permissions to install software, but that’s not the worst part. Blackra1n install of Icy breaks cydia and rock your phone since it has a very old version of dpkg. This is the core to all these installers. Since icy is usually installed last, it overwrites dpkg with its own. This causes things like winterboard not working, sbsettings not working. What is really happening is mobile substrate cannot be installed (among other things).
I get about 20 emails a day on various issues that all stem from this one issue. So please spread the word. Do not install Icy in blackra1n.
Note: Icy is not to blame here, but the installation of Icy on blackra1n. Icy bundle in pwnagetool is fine. The problem is Geohot found a very old Icy and did not get it from rip-dev guys.Mark Bruce & Kory Lee
