I know what you're thinking - Continuum? Wtf is that? It's that novelty phone released back in November of '10 with two screens: the actual display, and the "ticker" underneath.
When it was release, it shipped with Android 2.1 (that's Éclair for those who haven't been in the Android game for more than a year). Guess what? That hasn't changed. Yes, those poor souls who bought the Continuum have been stuck running 2.1 for more than a year.
