A first for Apple that it does not want.

FOX's Carmen Roberts reports:

Does it seem everyone you know has an iPhone? Maybe so and that's a problem for Apple.

It may face a dreaded challenge, a peak in iPhone sales. Signs suggest the smartphone sales for the first quarter of 2016 will drop for the first time and not just drop, but make an abrupt decline compared to a year ago. The question is does Apple have another blockbuster under its hat?

It may need one because the tech giant makes most of its money from iPhones.
