Here's how (and why) people are suing Apple for slowing down older iPhones

You may have heard: iPhone customers around the U.S. are suing Apple for slowing down their older phones. 

Class-action lawsuits have been filed in at least three states — California, Illinois, and New York.  Whether or not Apple violated any consumer rights is for the courts to decide. What is known at this point is that some people are disgruntled, though it's for all sorts of different reasons.
