Security guards and staff stand at the entrance of an Apple store during the release of iPhone 5 in Beijing's Wangfujing shopping district, 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.
