With just days before Apple is expected to unveil its new iPhone, AT&T Thursday announced its 4G LTE network is expanding into nine new US markets. The carrier also said it expects to add 43 more markets for the high-speed network by the end of 2012.
Although Apple's not talking ahead of the Sept. 12 media event, observers expect the Cupertino, Calif. company to introduce a new iPhone that supports the faster LTE networks. The new iPhone would join the latest iPad as two iOS devices compatible with LTE.
