I am getting the "Charging is not supported with this accessory" with the charger that came with my iPhone. I also am getting it with the car charger I bought from AT&T at the time I purchased my iPhone 4. I am currently running iOS 4.3.5. These were supposed to be Apple certified accessories. I have noted my wall wart (charger) will start working again if I unplug it then plug it back into the wall. I suppose I will have to go to AT&T and have them replace both units? Anyone else having this issue?
