An employee cleans an advertisement plate at an Apple dealership on the eve of iPhone 5's release, in Wuhan, Hubei province December 13, 2012. The China release of its iPhone 5 on Friday should win Apple Inc some respite from a recent slide in its share of what is likely already the world's biggest smartphone market, but its longer-term hopes may depend on new technology being tested by China's top telecoms carrier.
