If you have an iPhone and then become poor, sure. You probably won't get ahead much by getting rid of your iPhone. If you're already poor, then an iPhone (not a smartphone) is definitely a luxury.
There are capable smartphones for much cheaper then an iPhone that could get the job done. That's what GP was likely getting at.

I am not aware of a socialized plan to put phone in the hands of poor people, but they are getting increasingly cheaper. You can get Samsung Galaxy line (not the flagship model) phones from cheap, prepaid carriers. Wi-Fi is becoming increasingly available, which makes the limited data plans not that bad of a drawback.
