I bought a Alcatel with Firefox OS a month ago (Movistar here in Mexico) , I gave it to my father. He is very happy with it.
when i was there, i went to all movistar stores i could find (one per city block) and none had it. i ended up finding one in that part of mexico city, forgot the name, near the chinatown-street that has lots of electronic stores... anyway, there was a movistar store there, inside a parking lot, that had ONE open box alcatel one...
Took me 30min to buy, mostly because of the activation.
