There are some really cheap micro usb cables on ebay and I think they'll work with the x. I tried my wife's charger (usb cable w/ wall plug in) and it worked fine (not Motorola). Anyone know more than I do (which isn't much) concerning cables/charging please tune in. My thinking is that I can get a car charger adaptor that has the standard usb plug in and just use the micro usb cable to charge in the house and car. Is there supposed to be some kind of a smart chip in them? Thanks!!
