old iPhone (may have dead battery) (Blackburn)

I used an old iPhone for a specific app for a GB Wi-Fi inspection camera, but the battery blew-up and is no longer functional (it burst literally out of its case).

Unfortunately the app is not available for current android versions but apparently still on the Apple store for use on iPhones.

I am looking for an old iPhone that is no longer in use, that I can use for just this tool. The battery does not need to hold charge as long as the Bluetooth and Wi-Fi works.

No rush, I am just trying to make the tool usable again.

Thanks for looking.
