Only the last Danger device ran NetBSD; all prior ones used a proprietary, in-house OS. It didn't run any of the normal BSD userland, however, as Danger had its own Java-based userland and UI layer.

Danger was bought by Microsoft, however, right around the time the NetBSD phone was going to market. AFAIK the tech didn't continue much past the Microsoft acquisition. (Source: worked at Danger on the NetBSD project, but left shortly before the Microsoft deal.)
