For something as basic as a cable converter, the Lightning to 30-pin adapter sure is pricey. Each iPhone 5 user who wants to use their existing accessories will have to drop anything from $29 to $39 in order to get one from Apple. That is because the gizmo isn't a passive device – inside it is contained a tiny chip inside that handles digital-to-analog signal conversion., which is why the converter comes at a steeper price than one would expect.
But can a third-party accessory maker be trusted? Well, we cannot really say with absolute certainty until enough user feedback have been submitted. On one hand, unofficial 30-pin to USB cables have been around for years and have been working just fine. But on the other, you get what you pay for, so early buyers should proceed at their own risk before hitting that "Add to cart" button.
