Bonjour Pierre!
Le Fairphone est magnifique!
I merely went with Fido because they are the cheapest in Canada and I already had an account with them from my older phone. Before I even considered importing the Fairphone I went on their tech support chat line and linked them to the Fairphone 2 tech specs. After they reviewed them they said it was good to go I went ahead and made arrangements to have it shipped. I suggest you do the same, if you’re with a carrier already simply get on tech support. Don’t bother going to the kiosks in malls or whatnot. Not even Fido reps knew what the hell I was talking about.
I don’t download apps so I can’t say anything about that. With the open source os I might look into getting stuff… but I’ve lived with a “dumb” phone for so long I don’t really know what I’m missing. The UX is really well integrated though and it’s much simpler to use than any tablet I’ve had.
In many respects it’s a regular phone! Just guilt free!
