I received my HTC EVO DESIGN 4G for Christmas. I had doubts about the usb port being able to handle multiple daily in/out connecting to my Ipad or wall charger at one location and my Pc at my home. In May, the wall charger went intermittent and now almost impossible to get a charge connection. Next, the PC became intermittent for tethering. PC data cable charges fine but I have to work at moving HTC plug a hair or two for a data connection. I found this site in search for answers. HTC has a horror story of problem posts for usb socket problems going back to 2010. I'm going to try their warranty service. I wonder what good is that, if they only re-solder some connections? That usb connector needs replacement with an upgrade of quality. That little pin
connector should be secured to it's shell a lot better than those being shipped.
Recall them!
