Looking closely at the AT&T Charge only cable... it appears no different from a standard MicroUSB cable. 4 pins on the large end, 5 on the MicroUSB connector. What's the extra pin? It can only be duplicating voltage (or ground, which seems unlikely) to a 5th connection inside the device. The connector is too small for me to get anything inside to test continuity from one end of the cable to the other. Whatever is missing from this cable is partially responsibe since I can't make it cause the issue on any of the chargers I have tested... 50% of which cause the problem with any standard cable. Somewhere, inside this cable, at least one of the 5 pins is not connected to anything.
