Microsoft is spending hundreds of millions of dollars behind the marketing campaign for Windows Phone 7.
According to fiercedeveloper, "More than 12,000 WinP7 developers have now registered to market their applications via Microsoft's Windows Phone Marketplace storefront, slated to go live later this month.
According to Microsoft, WP7 developer registration increased close to 40 percent over the last month alone. Developers who requested early Windows Phone Marketplace certification have already published hundreds of apps in advance of the first WP7 smartphones, slated to hit U.S. retail outlets on Nov. 8.
On Nov. 3, Microsoft will enable self-serve Marketplace capabilities in an effort to enable additional developers to include their apps in the store at launch."
