Last month, Fujitsu in Japan unveiled the IS12T, announced as the world’s first cell phone running on Windows Phone 7.5 aka Mango. And the country’s second biggest mobile carrier (and exclusive provider of the handset) KDDI au, didn’t lose much time: the IS12T became available today over here (here’s Fujitsu’s official press release in English from today). As we reported previously, the Mango handset comes with a 3.7-inch LCD with 800×480 resolution, a 13.2MP CMOS camera, a water- and shock-proof body, 32GB internal memory, a microUSB port, IEEE 802.11b/g/n Wi-Fi (no tethering), DLNA support, GSM/CDMA, etc.
