Solarwind - what model and submodel of iPhone is it? Innards vary. Methods may not. For some reason I thought you had said iPhone 3 but I see you didn't specify. Maybe then a 4? IF resistors are used on data leads et al then a "genuine" charger and an ohm-meter and some playing and thinking may well provide an appropriate answer.
