After much rooting on countless sites, forums, etc. I am now become finally found it. The charging cable is actually working with the iPhone 3G. Many vendors have unreliable a charging cable offering that is only compatible with the old iPhone, but it written as compatible with 3G what. For a sloppy, as some Euros are quickly down the drain if the cable does not fit
Well finished, with click lock also holds securely when charging, what more could you want.
