Pornography, obviously. Sell it.

Maybe a highly controversial take .... using it as a phone?

use it as a phone, if and when needed

take pictures it's a really good camera. You can edit videos on your phone nowadays pretty easily with applications.

Sane people would sell it.

If you don’t want it then I will take it.

It's pretty handy, you can check your email too, and a cool calendar thing....

Play games on it?

I use mine as a flashlight, occasionally send and receive texts, occasionally use it to set up timers, and some times listen to audiobooks while doing other things.

I hate using phones, people who use phones as their primary way of interacting with the internet frighten me.

texting + phone call device primarily. calculator and flashlight in your pocket and maybe some mobile games if you're stuck somewhere with nothing else to do.

Take pictures and upload them to instagram or another site and you can find friends

You could always use it as what it's intended to be.... a phone to talk to send and receive calls

My parents both have iPhones. Other than texting or calling they use it for YouTube, GPS, looking at emails, use apps for banking, and ask siri questions they don’t know.

Steam Off Topic

I have a phone that I use for phone calls and text, I rarely carry it.
