A pair of new job listings on Apple’s website confirm that the company is seeking two engineers to overhaul the existing 30-pin dock connector currently employed by its iOS devices. The listings strengthen rumors Apple will introduce a new dock connector with its sixth-generation iPhone later this year, that will be significantly smaller than its predecessor.

While the majority of mobile devices now ship with micro USB connectors, Apple has remained dedicated to its 30-pin dock connector. But that could be about to change, with sources claiming future iOS devices will employ a “micro dock” that will be significantly than the existing connector.

See that adapter in the picture above? It’s an Apple 30 Pin Micro USB Adapter. And it might just prove that China is more important to Apple than Europe.
