Cool, I just saved myseslf hours of work on all my projects. The solution is:
/M[ProductCode]
You an create an uninstall shortcut that automatically updates, when the producct code changes by using the above code rather than the explict one that the InstallShield product itself creates. For those that use the /x method the principle should be the same.
