Google maps and YouTube are back and available so that was just a short term thing.
No they are not. Click on a Youtube link in Safari or email. Click on an address in Safari or email. Ask Siri to take you home and see if you get Google Maps. Until we can specify the app and make them default then they are NOT back. And why do I have to have two map apps taking up the very little room I have on my phone? The same goes for the newsstand, weather, stocks and passport.
