In my case it was a reference to the phone being so locked down that you can only go to Apple App store through iTunes (and yes through iPhone) but you can't go to different app stores.
With Android you can install apps on your phone from Google's "Play Store". And from Amazon's App store. Or you can just download the .apk file and install them directly without any app store. There are also a bunch of other random app stores you could use if you'd like to. I just don't like being confined Aoole's app store and needing to have iTunes on m computer to manage my phone from my computer.
