A sign of the new iPhone 5 is seen at the entrance of an Apple Store in the financial district of Pudong in Shanghai December 14, 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.
