Ooh, what do we have here? Japanese site Sumahon!! (a play on the word for "smartphone" in good, old Nihon) reports that HTC posted details about a new WiMAX-capable phone for KDDI to join the carrier's WiMAX Samsung Galaxy S II -- the HTC J ISW13HT. The company apparently jumped the gun, though, as the page has since been unceremoniously pulled -- but not before the aforementioned site grabbed some screenshots. According to the tale of the tape, er, phone, from the site, the ISW13HT rocks Android 4.0 with a coating of Sense 4.0, a Snapdragon S4 chip, 1GB of RAM and 16GB of internal storage plus a microSD slot. One screen grab also states that the phone has a 4.3-inch qHD display. Sizewise, the handset is 66mm wide, 132mm tall and 10mm thick. Weight is listed at about 142 grams. A visit to the official ISW13HT page reveals a "page not found error" but that likely won't be the case for long -- that "Spring 2012" grab probably wasn't created for kicks.
UPDATE: The site for the ISW13HT is active again so hit the source link for more details -- in Japanese, of course.
