Fujitsu IS12T running Windows Phone 7.5, name officially confirmed?

We noticed in the press release for the newly-official Fujitsu IS12T that the OS is in fact called Windows Phone 7.5. Then we spotted the above photo from Engadget and it also very clearly states the same name. Well it looks like it's finally time to retire the Mango codename because Microsoft's Windows Phone 7.5 is on its way!
