bonjour

The officially unlocked GSM version will work just fine. However, that model is currently only available through Apple's online store, I don't believe stock has reached brick/mortar stores yet, you'll have to check.

Why do you want to purchase in the US? Your warranty & support will only be valid in the US, and you can purchase officially unlocked iPhones in France that have an EU wide warranty. Doesn't make any sense to me.
