Microsoft Now Accepting Windows Phone Mango Submissions

Developers rejoice! The moment when you can submit your apps for Windows Phone Mango has finally arrived.

We noted last month that App Hub would begin accepting Mango apps in late
August. The infrastructure for accepting your Mango apps is coming online as we speak! Some of you may already be seeing new content as we conduct a final round of tests. Stay tuned for a more detailed overview of the Mango app submission process within the next 24 hours.

If your apps are ready for submission, get to it!
