So will this work with a iphone 4c?
There was no 4C, do you mean 5C? If so, yes, these will work. If you mean 4S, then no, these will NOT work.
Does this work with the IPhone 6s?
I received my “2 pack” today, only to discover there was only 1 cable in the package.
Please advise how I can get the 2nd part of my “2 pack” shipped out?
Sorry you’re missing a cable. Please email email@example.com with your order details and issue; CS can get you taken care of.
