> I'm using the base application for iOS created with the create script.  That works correctly.
 I add the Echo plugin example Objective-C code and everything compiles.  Then I add the JS
to call it and that's when things get weird.
> In index.js, after the var app = { ... }; statement I add:
> window.echo = function(str, callback) {
>     cordova.exec(callback, function(err) {
>         callback('Nothing to echo.');
>     }, "Echo", "echo", [str]);
> };
> Then in onDeviceReady I add the following after the receivedEvent call:
>     window.echo("echome", function(echoValue) { alert(echoValue == "echome"); });
> I run the app and I get the green glowing "Device is ready" message.  So we're getting
into onDeviceReady successfully.  But the "true" alert never pops up.
> Until I double-click on the home button.  Then when the running apps show at the bottom
of the screen, then the alert pops up.  I tap back into the app and I can click to dismiss
the alert.
> What's going on here?  It seems like the example plug-in should work a little better
than this.
> The reason I'm doing this at all is that I'm seeing similar behavior in my app that I'm
currently failing to upgrade from 2.1 to 2.2.
> Worse: If I single-click the home button and then go back to the app, I get the alert
pop-up, but after I click on it the screen goes black.
> Any help would be greatly appreciated.
> Thanks,
> Aaron
