I use it around the house to Airplay music to various devices.
A number of things don't work, or work in unexpected ways, mostly because Apple doesn't allow me to log in to iCloud with such an old phone.
I can't control lights with the Home app. But Airplay works fine. The phone doesn't know what a HomePod is, but it shows up with a regular generic speaker icon, like the AirMac I have hooked up to my stereo.
Sometimes I have a few minutes to kill, and I pick it up to look at HN. The New York Times web site starts to work, but the login page doesn't load at all. WSJ blocks me at a "verifying the device" screen. WaPo half works. eBay works some, but no pictures. Ditto for Wikipedia.
There's a lot of things you take for granted on a new phone that you only realize when you're using an old phone. Like you didn't used to be able to quickly scroll an entire web page it's only a screen at a time in iOS 10. You can't grab the scroll bar on the side and move it, either.
And 99.9999% of people don't realize the genius of the camera island. It makes it so much easier to pick up the phone if one end is elevated a bit. With a completely flat phone, you end up dragging/scraping it along the table in order to grip it, which scuffs the surface. And if the table is really smooth, it's surprisingly difficult to lift the phone straight up.
Why can't you log into iCloud? unless somethings changed in the past year or something broke between ios 6 and 10, it should work. I'm still signed into my iPad 2 running iOS 6 (granted, iirc the root cert expired a bit ago so you need to update that). the 2fa is also a bit weird, you have to input the code after your password (eg: if your password is password123 and the code is 789 you'd submit password123789)
I think that might be a thing with apples Advanced Data Protection if you have it enabled, which is understandable since the software needs to know how to un-encrypt the data. If you don't have that enabled, then ignore this and assume apple decided to kill a whole lot of devices (particularly their macs, I know a surprising amount of people still on 10.15)
