I bought two replacement charger cables (USB - dock connector) for the iPhone4. I was able to charge with the two of them without problems until recently. I'm now getting an error message saying that charging is not supported with these accessories if I try to use them with a MacBook Pro.
Charging is not supported with this accessory
What's interesting is that I can normally charge with both replacement chargers on my PC, without any errors. What's going on?
Is this a "feature" of some update?
