It seems that one with the resources of the fbi should be able to reverse engineer their own version of iOS and push it out onto devices via a local network spoofing the apple update servers. They would likely need some of apples private keys in order to trick the device that it was a legit apple server/update. But getting those seem a lot easier to get, and could draw alot less attention.

Get a job working for your university's new media or IT department doing web development. That's what I did. My degree isn't even in CS and I was able to get a job offer, as a web application developer, after college. I got to hone my HTML/CSS skills as well as become familiar with ColdFusion. I ended up going a different path. But by working there it would get you experience you could put on a resume. It's all about getting your first job. After that it seems like the degree matters less and less. I would imagine getting a CS degree would help on the web developer front though.
