I bought this set because there were reviews that said it was also 3G-capable. fallacy !! it does not fit in the holder, it is not flat enough. Now is the set in the cabinet and has to wait until I next year the new iphon earn. I can therefore only judge the cable, it works super well even with my 3G, and keeps fit without problems even on rough roads. the bag I do not really need, I have a flip case.
