I finally decided to update to Xcode 4 today and the first thing I had to do was get the look and feel back to normal. This involved converting my old themes to the new Xcode 4 format. Because we previously shared the “ǝɹɐǝqʎǝuoɔ %}” theme, we thought we would do the same here:

mkdir -p ~/Library/Developer/Xcode/UserData/FontAndColorThemes; cd ~/Library/Developer/Xcode/UserData/FontAndColorThemes; curl -O http://files.urbanapps.com/ǝɹɐǝqʎǝuoɔ.dvtcolortheme

Enjoy :)
