We reported back at the end of August that Microsoft had just pushed back the Mango update to September 15th. We really did not know what that meant at the time, but saw quite a few other clues to suggest that indeed on that day, something big was afoot.

Of course, we all know what happened. September 15th came and went and Microsoft made no announcement at BUILD, nor updated their site to show us "Where's My Update?" or anything really. Finally, Microsoft's Joe Belfiore came out and said it was just a rumor and "we've always said fall". Since then, we've seen some major apps and Xbox LIVE games get updated, Taiwan roll out the update and imploring devs to update their apps to boot. We still maintain that something was to happen on September 15th and now that seems to be confirmed.

In the leaked Orange France memo, which is too detailed not to be real, the very first paragraph states:

"A partir du 15 septembre 2011, nos clients utilisateurs des mobiles WP7 Orange pourront bénéficier de la mise à jour en WP7.5 (intitulée Mango). Les mobiles Orange concernés => HTC Mozart / LG Optimus 7 / Samsung Omnia 7"


"As of September 15, 2011, our customers WP7 Orange mobile users will benefit from the updated WP7.5 (called Mango). Orange mobiles concerned => HTC Mozart / LG Optimus 7 / 7 Samsung Omnia 7"

What seems to have happened is there as a last minute decision to forgo Sept 15th as the "launch" day (even if it was a limited rollout), hence why Belfiore didn't just dismiss the rumor days ago (which would have been easy enough to do). Instead, it looks to be pushed back by about a week...more on that later.
