They even actually re-released a version of the 3310 a few years back. I still have my old Garmin knocking about, wonder if it’s got updated maps if I got a model without GPS.

Android is already based on Linux. But in general there are FOSS phone OS’s. GrapheneOS being the dominant player

I started joking that my next phone will be a Nokia 3310. I feel more and more each day like that should just be my actual next phone
