Looking for big iPhone changes? Wait till next year

This is supposed to be a year of big changes for the iPhone, but all rumors so far point to minor tweaks in Apple's iPhone 7, which CEO Tim Cook is set to unveil Wednesday before a few thousand people at an event in San Francisco. And the biggest change -- the removal of the headphone jack -- is something that could tick off a lot of people.

Every other year, Apple releases an "S" model of its popular phone, where the S often stands for "same old design." That was the case last year with the iPhone 6S, which looked identical to 2014's blockbuster iPhone 6. The only noticeable design update: a new "rose gold" color option

Besides getting rid of the headphone jack, other changes in the new iPhone device might include more storage (the low-end model may start with 32GB instead of 16GB), a better camera and better water-resistance. Those features may be enough for people to upgrade from a current iPhone and for people who want the newest iPhone. But for others, who now have to buy their phones outright for about $649, or for those who are fine holding on to older models for more than the typical two years, Apple's iPhone 7 may be a tough sell.
