MLC Chat is a great iPhone app for running models (it's on Android too) and currently ships with Llama 3.2 3B Instruct - not the version Meta released today, its a quantized version of their previous release.

I wouldn't be surprised to see it add the new ones shortly, it's quite actively maintained.

Seems much more stable than the last time I tried it too

I access them by running the models in Ollama (on my own hardware), and then using my app Chaz[1] to access it through my normal Matrix client.

I'm on Android, however my somewhat elaborate solution was to install Ollama on my home laptop computer and then ssh in when I want to query a model. I figured that'd be better for my phone battery. Since my home computer is behind NAT I run yggdrasil on everything so I can access my AI on the go.

I've been using PocketGPT.
