I'm in the same situation really but have a feeling I won't get the opportunity to use it much now. I also learned Flash on my degree course. At the time it was AS 2.0, but I've re-taught myself AS 3.0 so have very good knowledge of both.
Luckily I can work in Flash pretty quick so although I don't possess the HTML knowledge for building and developing websites, I regularly do mock ups in Flash so my clients get a feel of how their site might look and work. Which I can then pass on to a developer after.
But as annoying as it is, and like the above poster said, Apple have already said they're going to begin stopping mobile Flash development. They've already steered away from it on the iPad.
And now that HTML5 can do pretty much what Flash was designed to do, but better, Flash, online at least is on it's way out.
