How do I handle the custom URL scheme in PhoneGap for a cold start?

I use handleOpenURL () for a special URL scheme to launch my application from a link in an email. Works fine and I can do things in my application based on the URL parameters in the link.

The handleOpenURL () problem does not seem to cause a call when my application starts a cold start (does not work in the background). Is there any other handler that I can use for cold start compared to an already running instance?

OR

Is there a global variable that I can read that will tell me what the call url is? I read about invokeString but it never seems installed?

I am using Phonegap 2.0
