I've upgraded to XCode 4 and because IB is now inside none of my old NIB files will open getting a "An instance of ASKNibConnector could not be decoded" error. Is there a way to convert NIBs to XIBs without interface builder? or do you have to do something like reinstall 3, convert the nibs and reinstall 4?

To convert your nib to xib format, use the command line tool ibtool like this:

ibtool foo.nib --upgrade --write foo.xib

Or use this gist to find all your nibs and convert them: https://gist.github.com/254161
