Nokia has been trying to maintain an Apple-like secrecy over its upcoming Windows Phone, but one of the attendees didn't get the memo, despite an explicit plea by Nokia CEO Stephen Elop. "This is something that is super confidential, and we do not want to see this out in the blogosphere."  Well, the cat is out of the bag. Technet.hu has filmed the handset codenamed "Sea Ray", revealing a phone that looks very much like the N9.

The phone has a dedicated camera button, as is standard in all WP7 smartphones, and will be running Windows 7 Mango. The first Nokia WP7 phones are expected to launch by Q4 this year.
