Microsoft has begun sending "Save the Date" invitations for an upcoming developer summit to select Windows Phone programmers.
The two-day summit is slated for June 20 and 21 in San Francisco. I've asked Microsoft officials if and when they plan to open registration to interested developers who don't receive the "Save the Date" invitations. No word back so far.
A Microsoft spokesperson said: "You should expect a formal registration process as with most events. Will have more details in the coming weeks."
Company officials have continued to refuse to comment as to whether existing Windows Phone devices will be upgraded to the Windows Phone 8 operating system. I have heard from my contacts that no current Windows Phones, even more recently introduced models like the Nokia Lumia 900, will be getting Apollo.
