The latest update to Windows Phone, code named Mango and officially known as Windows Phone 7.5, is widely expected to make it’s official debut any minute (hour/day) now.  Given that the last update, code named NoDo, was beset with distribution problems as OEMs and mobile operators “tested” and “scheduled” phone updates before delivering them, causing some users to have to wait many weeks or months in order to officially get the update, we’re only cautiously optimistic that “Mango” will provide a better update experience.

This time, everyone seems to be pretty upbeat about the whole thing, at least so far.  Officially, Microsoft has only blogged that the Windows Phone update will occur “in a week or two” (from Sept. 21), and that an updated “Where’s My Phone Update page (US or International) would be revised to include the Mango updates, something that hasn’t happened yet.

Still, everyone seems to have settled on the September 27th date as “Mango Day”, and that sounds good to us.  Windows Phone Secrets author Paul Thurrott tweeted as much the other day:

along with numerous blogs also pinning the date as the start of Mango’s update process.

And if you didn’t jump the gun and *cough* already roll back your Developer phone in preparation for the official update (the developer bits came with numerous warnings to back up your phone as you would be required to roll back before moving on to the official update), there’s some good news coming from Windows Phone Director Brandon Watson:

However, if you didn’t get your pre-release Mango update from official Windows Phone Developer channels, the news probably isn’t as good:

So, hopefully, in the next few hours or days, we’ll be officially entering the Mango era.  Let’s hope it goes a lot smoother this time!
