Estoy recibiendo estos dosadvertencias de hilo compilar en un iPhone (iOS 6):

THREAD WARNING: ['InAppBrowser'] took '260.519043' ms. Plugin should use a background thread.
THREAD WARNING: ['Geolocation'] took '110.953857' ms. Plugin should use a background thread.

Así es como llamo a los complementos en mi código:

window.open("http://www.anaddress.com", '_system');

y así es como se ve mi config.xml:

<?xml version='1.0' encoding='utf-8'?>
<widget id="my.id" version="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0">

    <feature name="Geolocation">

    </feature>
    <feature name="InAppBrowser">

    </feature>

    </author>
    <content src="index.html" />
    <preference name="fullscreen" value="true" />
    <preference name="webviewbounce" value="true" />
</widget>

Por supuesto que instalé los complementos utilizando la CLI de cordova:

$ cordova plugin add org.apache.cordova.inappbrowser

¡Cualquier ayuda será apreciada, gracias!
