A Nexus One? Really? https://developer.mozilla.org/en/Mozilla/Boot_to_Gecko/Setti... suggests that only Nexus S, Galaxy S2, and the Galaxy Nexus are listed. There's also a note that "only devices running Android 4 (aka Ice Cream Sandwich) are supported," where the Nexus One is stuck at Gingerbread.

If this has changed, I'm really, really excited. :)
