I took the phone to right next to the source of the internet signal, then reconfigured the connection by:
Wireless & Network
Wi-Fi
My Connection
After Forgetting and entering in the password, I got a connection with the default browser.
I then went to
https://f-droid.org/ and downloaded/installed f-droid app.
From there the only thing I had to do was find the app I wanted from within the f-droid app.
But for reference, where are some good resources to find tutorials on how to use replicant phones? Nothing I can find of substance from a regular startpage web search!
