This year's WWDC came and went without the appearance of a new iPhone, breaking with years of tradition. This disruption to Apple's established released cycle, combined with other factors, may be upsetting some portfolios. "People are concerned about Apple's growth peaking, Steve Jobs' health and the delayed launch of the new iPhone," Brian Marshall, an analyst at Gleacher, told MacNewsWorld. Nonetheless, Apple is "massively undervalued," Marshall said. In fact, the wait may pay off with the release of not one, but two new iPhones this fall.
