You want to get a device with @iode preinstalled, but it is a bit of a stretch for you to consider buying a premium-tier device for your first venture into a #degoogle lifestyle?
We hear you! We are creating the OnePlus Nord N20 5G images for #iodéOS right now!
These phones have 6GB RAM, a *headphone jack* and a *sd card slot*. This combo is hard to find, but it is also going to be one of our most budget friendly offerings!
Look for it in the next few weeks: https://openmobile.us/store/
