Don’t install Xcode 4.2 developer preview (build 4C104) on your production computer, even in another folder. I just did and it broke the code signing ability of my Xcode 4.02! Re-installing Xcode 4.02 did not help… So the only way to get back to work was to remove ALL devtools using this terminal command: sudo /Developer/Library/uninstall-devtools [...]

Now how do you now create an app that will run on 3.0 – 3.1.3 devices? After some research I found the (easy) solution: In Xcode, go to “Project” – “Edit Active Target” – “Build” – “Deployment” Change “iPhone OS 4.0″ (or 3.2) to whatever minimum version is needed by this app. Done!
