I've never hung onto old cellphones; when upgrading I usually give the old one to the provider of my new-one so they can transfer my contact-lists etc over to the new one, then let them recycle the old one for me.

I _do_ still have one aged Nokia "Featurephone" from about six years ago though. It's great to prop in front of my 'remote' field-strength-meter (several wvelengths away, down in the forest) when doing antenna experiments, so I can make a video-call to it and see the meter. So much more-convenient than the old method which involved a telescope and was often impeded by foliage.....
