I just got an Advanced from BHPhoto and the box says 1080p cam on the side. I bought it because I thought it was 2.7k...did I get the wrong model? Also, save for the fact that box seems like it was opened once (I haven't opened it yet personally), I know that sometimes there are good versions and bad versions of hardware. Are there good and bad versions of the Advanced? Any telltale signs that would indicate as such?
