Yes, I know Mobile Joomla 2 is more up to date.
But the mobile smartphone template has been changed, I wish to avoid having to re-customize it all from scratch, and adjust every single item position, it takes a lot. Furthermore, I don't like the new vertical popup menu and sidebar, they force me to re-think the whole site interface. Consider I run other sites with Mobile Joomla, I'd have to restyle them from zero in order to update the component, and I've got many other things to do currently. I've tried duplicating the MJ 1 smartphone template prior to installing the new version and then using it in MJ2: of course, I'm getting blank screen...
So I've currently reverted to the old MJ version, although this can't be the definitive solution. If you have any workaround to suggest, tell me. Thank you.
