Just the other day it was revealed, surprisingly, that KDDI of Japan (via their mobile operator brand 'AU'), will be launching the Fujitsu-Toshiba IS12T (still love that name!) in July. What makes this big news of course is that this will be the first "Mango" device in the world to go on sale.

Now we're getting word that KDDI, Fujitsu-Toshiba and Microsoft Japan are set to make it official by having a press event on July 27th. Evidently media invites have gone out and yes, they plan on showing off and announcing the pink-n-waterproof handset for the Japanese market--the first Windows Phone for Japan and the first worldwide with Mango.

Combined with that Nokia Sea Ray leak and confirmation that it is running Windows Phone 7 build 7710, which is RTM and guess what folks? We're pretty sure Mango is way, way closer than we thought.
