I threw up the cordova rc1 on my dropbox. You can check it out at https://dl.dropbox.com/u/175074/cordova-2.4.0rc1-src.zip. I will be releasing PhoneGap 2.4.0rc1 on the pg site tomorrow and hopefully get more people testing our RC's. PG 2.4.0rc1 is available at https://github.com/phonegap/phonegap/archive/2.4.0rc1.zip
