What do people do on their iPhone all day?

When ever I get on the subway I always see a lady literally staring at her iPhone the whole time and usually her thumb is going up and down the screen and I just wonder what these people do on their iPhone the whole time.

Probably scroll through their apps all day, thats all you can do on an iphone;)

Texting, reading news or sports, reading books through ibooks, reading newspapers…
