Is there a way to tell by looking at a box or phone (920) whether It's an early production model or a newer one?

I join the thread, my box says 920.1 though if that matters.

just got mine last week and it says 920.3

Both my Red and Yellow say 920.3

Looks like the 920.1 are the early models, I would say folks with those models purchased their phones closer to launch. I bought mine within the last couple weeks and both are 920.3 models meaning most likely from the latest batches.
