iTunes requires usb drivers to sync with an iPhone. Wine does not support windows usb drivers so even if you get iTunes to work in wine, connecting to the iPhone with it won’t work. You might be able to use libimobiledevice to do a backup.
There is an XML API endpoint that could be parsed by a terminal RSS reader like terminews. For more information, the documentation is here. That being said, this would be read only. MLMYM does seem to be somewhat usable by lynx and w3m in the terminal too... this comment was posted using lynx and MLMYM.
Edit: although it looks like it posted in duplicate lol.
Here you go!
