Look into tophone queue for the received packet.

- only works if we don't have a phone connected, but that is probably dsired
- this will send a copy of device-originating text messgaes to a connected phone. Breaking change.
- this will iterate the tophone queue by deconstructing and reconstructing it every time we look for an ID. Probably also mangles the queue oder since it aborts when a ID is found.
- Can we navigate the packet pool instead? If so, how?
- Let's keep this in draft state for now
