Looks like the earlier rumors about a GSM version of the HTC EVO 3D were right on the money after all. HTC France mentions in its official Twitter feed that the EVO 3D will be coming to France at some point in the future. Though not specifically confirmed, this likely means the EVO 3D will also see a wider European release.
Here's a translation of the tweet in question. Hit the source link for the original French.
"You want a HTC EVO 3D for France? So do we! It'll keep the same name, too. Release date has yet to be confirmed."
