Justin, I believe SC stands for 'spurious chinese'!! `I think it's actually 'Sciphone', but this is not an Apple iPhone, just a cheap copy - and I believe you can get them a lot cheaper if you are inclined to buy counterfeit goods (in fact, someone is selling one on the ML forum for €100!!).
Edited to say: As far as I know, Apple do not make a dual sim iPhone - although you can apparently buy dual-sim cases and adapters for it, but not with very good reviews.
