Looks like Radio Shack may be expecting a nice little shipment of HTC Vigors in their stores come October 20th. This leaked document also shows the Samsung Stratosphere (Epic 4G) arriving on October 6th. Last we heard, the HTC Vigor could launch as the Droid Incredible HD and early leaks were showing it for an October 13th launch. So either Radio Shack has a more up-to-date launch date, or they’ll get it a little later than everyone else. Either way, the battle for best 720p Android device is on this holiday season!
