We previously covered the leaked Orange memo that pinned the 15th of September as the roll-out day, but we are all ware of this day passing by. Now, Microsoft has finally released some more detail on the actual window for release. Eric Hautala published the following over at the Windows Phone Developer blog:

For months, we and dozens of our partner companies have been laying the groundwork for the Windows Phone 7.5 update and making solid progress. As a result, we now expect to start rolling it out in the next week or two. At that time, we?ll also refresh the Where?s My Phone Update table to reflect the worldwide roll out status.
