I've used MDM to make my iPhone dumb. It's great! I wish there was an easy way to publish my configuration so others could use it / adapt it, but it's a little involved because you have to wipe your phone the first time you set it up with configurator.
I did that when I had an iPhone, I agree it was excellent. More people should do it.
Looking forward to MDM support on GrapheneOS.
Can't you use a config profile and enroll it ?
Supervised devices cannot be backed up and restored to supervised devices. You can only backup/restore to an unsupervised target. If you want supervision, you have to abandon your backup.
It sucks.
Is that iCloud iPhone backup and local backups?
I don’t use iCloud, so I don’t know.
I’m curious about this, what did you do to make it dumb?
I used Apple Configurator on my mac to supervise my iphone. Once that's done, you use configurator to add a profile to the device that (1) contains an allowlist of apps that can be used and (2) an empty allowlist of websites that can be visited. #1 means you can't use any new apps, and #2 prevents the ability to browse the internet by sending links to yourself in e.g. messenger or whatsapp.
This might be how they did it:

Interesting. But the list of apps on there is huge! Is it really still a dumbphone? Tha just looks like the apps I already have on my phone, and I still feel like I use my phone too much. What other apps do people have that are so addictive? Games, socials?
