There used to be hackish methods of getting stuff from PC to phone without iTunes. I remember this back with my iPod touch 3rd gen. I guess what we'd need to know to help you best is, what aspects of iTunes are you trying to fill with other software. If you are looking for one complete package that does it all, I'm gonna have to say no, at least, not to my knowledge. But, there are plenty of software choices to play and manage media libraries. The problem tends to be the way Apple and iTunes locks you out of everything. They've sort of backed off of this to a degree, you can actually get to your media now with readable titles. Before, the folder and file names used to be random hashes. SO it would be work to get everything out of iTunes, and that's assuming that all goes well, and that you won't stumble on some road block I haven't thought of, which is very possible.

Sorry for the long winded post, but I think the issue is a bit more complex than a single piece of software, depending on what you want to do.

I think if you put music in the Automatically Add to Itunes folder, it will sync the next time you connect your phone. That used to be the case, anyway. I never keep music on my phone, so I don't really know what the best options are, sorry.

Thatguy, could you give that version to me somehow? Thanks in advance.
And post 1, well, i have the same problem, although i use the app called Musicloud to store music on my phone, and it doesn't need iTunes, fortunately. But would be good if i could transfer through that one as well, because then Musicloud wouldn't take this much storage. And would be good to have that 12.7 thing cause as Thatguy said it would be easier to transfer ringtones...

I can upload the 12.7 version of iTunes and send you a link here pretty soon. I would do it now, except for that I ain't got my hard drive with me.

There's also waltr2 as an alternative, and from what I hear it works well for transferring to apple devices.
Note that I've not tried it myself as of yet, so can't comment further.
HTH,

{Personally, I grappled with Itunes for two years and then threw it out in 2014 in favour of buying a victor Stream, and I've never looked back.

Firstly being able to transfer stuff just by plugging the victor into the usb and copying, and secondly not having all that artist/album/genre crap, even when I'm listening to audiobooks is well worth having the extra device, and I certainly have no plans to buy stuff through a proprietory service like Itunes or apple music which forbitds me from listening to it on another device, or even owning it.

i use my Iphone for contacts, games, useful aps and many things, but with Apple's media locking policy I just find it far easier to have a separate device myself.
