phonegap/ios-sim was changed to take --devicetypeid instead of --target. So when running a command like: phonegap install ios --emulator you get errors like:
Usage of '--family' is deprecated in 3.x. Use --devicetypeid instead.
Usage of '--retina' is deprecated in 3.x. Use --devicetypeid instead.
I think this pull request should cover it.. https://github.com/apache/cordova-ios/pull/107
There seems to be a problem with phonegap-cli that you can't pass arguments to override devicetypeid (or formerly --target) but that's for a separate issue I think.
