How young is too young to own a smart phone? I was shocked yesterday to see a new survey that said some kids, I mean babies, have a smartphone! Really?

The new study by ZACT, a new wireless phone service, shows that 25% of kids ages 2 and under own a smartphone.
 
The study also showed that  25% of children ages 2-5 have a smartphone, while nearly 40% of children 6-9 own one! Who are these people?!

Just wondering if the parents are giving these children a smartphone as a toy?

Am I just totally out of the loop here or is this just too young?
