As you said, "try". My AT&T branded & subsidized HTC One is legitimately unlocked. And I have android 4.3 running on it while AT&T is still dragging their feet on 4.1.
I personally don't buy the urban legend that firmware updates are slowed by carrier testing. The carriers are too cheap to do real testing. Updates are delayed for one reason. Costs.
All you have to do is look back at the devices released with bugs. My Droid DNA on V had a bug where the wifi mobile hotspot would periodically drop out (meaning connected devices would lose connectivity). This bug was 100% repeatable and 100% persistent. Only took 5 minutes on hotspot for the problem to occur. Brian Klug from anandtech feels the same (via tweet) since mobile hotspot isn't working on his at&t review unit.
Not sure I get what you're saying here. How does delaying a firmware upgrade affect the carriers in terms of costs? Also, how does the Android upgrade model affect the upgrading of Windows phones?
