In the near-term, however, attention will be focused on Apple's likely iPhone 5S. Earlier this week Apple sent out invites to an event at its headquarters, which is widely expected to mark the new phone's debut. Underlining the importance of the Chinese market, Apple also sent out invites to an event in China on the following day. The event at Beijing's World Trade Center could herald the arrival of a low-cost iPhone, dubbed the iPhone 5C, a deal with China Mobile ( CHL), or both. Shares of Apple, which have dipped 6.51% this year, gained 0.45% to reach $497.55 during Friday trading. --Written by James Rogers in New York.Follow @jamesjrogers >Contact by Email.
