Omnia 7 users in France and who are on SFR will be happy to note that you should be getting your Mango update today. As noted on the official Windows Phone Blog, Eric Hautala details a bit about the update and tries to reassure others who own phones that are still "in testing" to sit tight, your update is coming too.
Not much else to say on the matter outside of plug in your phones and check for that Mango!
