I started having this issue three days ago. Launch day hardware version 003. Grabbed the USB cable from my Palm Pre and plugged it into the HTC wall charger that came with the EVO. Working fine so far. No longer a loose connection...it feels solid. And it doesn't quit charging if I move the phone while it's plugged in. I really feel for those of you that have a faulty charging port. Hopefully everyone gets taken care of once the hardware problem is fixed by HTC.
