the flood of HD7 activity, but details about the 4.3-inch Windows Phone 7 device keep leaking out. Today, an O2 Germany tipster blew off most of the remaining doors. We've got what appears to be a full spec sheet confirming a 1GHz processor, 8GB of storage and 5 megapixel camera but also detailing internal memory, a full complement of sensors, quad-band radio frequencies, 802.11 b/g/n WiFi and more. There's also a few pictures sizing up the HD7 alongside a Galaxy S, a training slide for the hopefully-more-than-a-marketing-buzzword "Dolby Mobile Sound," and for what we believe is the very first time, a cameo appearance on video. Our tipster says it'll launch in Germany in just two weeks at €559 (about $770) or €79 ($109) on a two-year contract. Tempting, no? Video after the break.
