There is this book by Mariana Mazzucato: The Entrepreneurial State: debunking public vs. private sector myths

I haven't read it, but from the TOC, it looks like these are the technologies that are "invented" by public sector that the iPhone (and other smartphones) rely on:

* Giant magnetoresistance (GMR), SPINTRONICS programme and hard disk drives

* Solid-state chemistry and silicon-based semiconductor devices

* From capacitive sensing to click-wheels

* From click-wheels to multi-touch screens

* Internet and HTTP/HTML

* GPS and SIRI

* Battery, display and other technologies
