Jetpack Mobile Theme Customization

Hi, I’m trying to find *this* file in the Jetpack Mobile Plugin so I can customize my WordPress.org site’s mobile theme:

“The theme files are in plugins/jetpack/modules/minileven/theme/pub/minileven/. However, if you modify the files directly, your changes will be overwritten the next time you update Jetpack.”

So far, I haven’t had any luck finding this file… The closest I’ve gotten has been to click “edit” under Plugins, thence getting to jetpack/modules/minileven/minileven.php and jetpack/modules/minileven.php but no luck finding the mobile module theme!! I know Jetpack has been updated since the reference I quote above was written, so that may figure into my problem.

How can I locate this file? (assuming, of course, it’s not unlocatable…)

Thanks,
Adele H.
