iPhone 8 sales are forecast to be blockbuster

See how Apple's iPhone ignited the evolution of mobile devices. Analysts are expecting a big overhaul and blockbuster sales for the next iPhone. SAN FRANCISCO -- The most significant update to the iPhone in three years promises not only to upend the smartphone market but Apple's financial results for several quarters. On the heels of the iPhone's 10th anniversary this week, and before Apple unveils its expected new models in September, analysts expect flat year-over-year iPhone sales as consumers wait for the revamped phones. After that, however, they expect record-setting sales, dwarfing the success of the wildly popular iPhone 6. Angelo Zino, a senior equity analyst at CFRA, predicts record iPhone shipments of 241.5 million in the 12 months following the iPhone 8 launch -- smashing the previous high, set by iPhone 6, following its introduction in late 2014.
