A ban on Qualcomm chips could have upside effect on iPhone sales. Or so the logic goes.

The order will not affect the introduction of Apple Inc.'s iPhone June 29. AT&T Inc. has exclusive rights to carry the iPhone, and the gadget's first version uses the carrier's EDGE network, which is not covered by the ITC ruling. Apple doesn't need a lift from its competitors' woes anyway, said Michael King, an analyst at Gartner Inc. technology research firm. "There so much hype around the iPhone that I don't think they will be able to produce enough to meet demand, so this won't help much," he said.
