I installed iOS 6 today on my iPad and iPhone. The "Maps" app is no longer "Google Maps"; it is now "Apple Maps". Fine by me, except all the street names here in Barcelona have the actual Catalan names replaced with Spanish equivalents.
For example, my street is no longer "Carrer de Bailén" but is "Calle de Bailén". The nearest cross street is not "Carrer de Córsega" but is "Calle de Córcega".
My office seems to have moved from "Passeig d'Amunt" to "Paseo Amunt".
This is somewhat inconvenient for me. For the native residents of Barcelona it is probably insulting.
