There is a positive result from the ongoing Facebook saga. People are starting to question what data is collected about them. This is an excellent review of the challenges presented with data tracking.
Fortunately for the person with the iPhone, those 600 apps had/have much more limited access to the inner workings of your phone. So while the data collected is likely quite substantial, it will be nothing like an equivalent user with an Android phone; Android is, unfortunately, willing to pretty well provide everything you do on the phone to any app.
It will be interesting if the sentiment in privacy starts considering iPhone vs Android phone privacy. As of today, the privacy of an iPhone is substantially better than Android.
