Why are they called 920 and 820?

Sorry if you expected a funny joke, but this is actually a genuine question.

We already have the 800 and 900, but why 820 and 920? Would 810 and 910 not be a more logical step?

Also, whatever happened to the 1001, was that just a product name and changed into either the 820 or 920?
Thanks!
