Launching app in background in iPhone
<p>Is there a way that I can use the url scheme approach to launch an application in the background or if it is already running in the background invoke it without it (the callee) coming to the foreground? I heard that this can be done in iOS 4.2 but don't see it when I use </p>

<p>[[UIApplication sharedApplication] openURL:url];</p>

<p>to open the application.
Thanks,
N.</p>
