Well, we can't say we didn't see this one coming. Fujitsu Toshiba mobile communications -- now there's a mouthful -- just unveiled the IS12T: Japan's first Windows Phone 7 device, and according to Microsoft prez Yasuyuki Higuchi, the world's first Mango handset. The sexy and IPX5 waterproof (!) 3.7-inch WVGA slate is powered by Qualcomm's MSM8655 CPU of undisclosed clock speed (which we've seen running at 1GHz in the Incredible 2 and Thunderbolt), and goes on sale in "September or beyond" on KDDI's au network. The pink gizmo packs a 13.2 megapixel camera with autofocus and has a plentiful 32GB of flash storage for housing whatever content you'd fancy toting around. The usual Bluetooth (2.1 + EDR) and WiFi (802.11b/g/n) suspects are also onboard. Interest piqued? Peruse the gallery our Engadget Japanese brethren have handily tossed our way.

Update: In addition to pink, it'll reportedly also come in a yellowish / greenish hue, as well as jet black.
