Thank God I thought I was allone
This fix will probably require that you edit the files again after each update but you can edit the core mobile theme.
DO THIS WITH EXTREME CAUTION AS CORE THEMES ARE TOUCHY FOR THE UNINITIATED.
Theme folder to customize
/wp-content/plugins/jetpack/modules/minileven/theme/pub/minileven/
Personally i think above should be linked to the primary theme folder so you can select and edit a separate mobile theme but hey maybe after 2.0 we will see some more changes
