Comment 13 for bug 1240875

We have the wizard now, so things work as expected on first boot. I don't think we should spend any time on live-switching locales (except maybe for 12h/24h clock?), as it's not something you ever really do on your phone.

The settings app should probably just recommend a reboot/session restart after you change your locale and warn that if you skip that you'll only see newly started software in the new language?
