Samsung Galaxy S II with WiMAX stops by the FCC on its way to Sprint

This Sprint-bound Galaxy S II already posed for one candid and now it also appears to have made a tour of the FCC's testing facilities. Packing CDMA and WiMAX radios, along with a design that matches the leak and and an appropriate model number (SPH-D710), this definitely appears to be the Within we were expecting. So far the only additional clue teased from the FCC documents comes from Wireless Goodness which points out it's 5mm taller and 3mm wider than Euro-spec Galaxy S IIs, but feel free to click the source link and look for yourself.
