Question: 1. What ubuntu applications provide support? (guides, how to's, status)
2. Also, specifically, details on support for syncing music to iPhone's and iPod's with the latest OS version:

	* Can you sync music to apple devices using >iOS4? (iPhone & iPod)
	* What applications allow you to do this and how? (guides, how to's, status)

### What has already been established is:

* Apple does not support Linux and has no plans to.
* [libimobiledevice](http://www.libimobiledevice.org) provides some support, however it currently **does not** support music/video synchronization with devices `>iOS4`. Go to [libimobiledevice](http://www.libimobiledevice.org) and scroll to the section titled "**[Status](http://www.libimobiledevice.org/#status)**" to see if your device version is supported.

Answer: 
Apples support of Linux is non-existing. There is not a single version of iOS that supports Ubuntu. Please file a bug with Apple.

Also, Apple frequently uses obfuscation techniques, which are likely to break the music database on iDevices. 

RE: I just want to add here that I have filed numerous bug reports with Apple, also mentioning that I refuse to have Windows and therefore have Linux Ubuntu installed on my laptop as well as owing iPhone3, iPhone4, iPhone5 and an iMac and that it's quite frustrating that I can't use my Ubuntu to at least manage my music and so on...
They have never replied a single letter, never mind any explanation and all that ignorance is pretty frustrating to the point that I will probably switch to Android device next time I`m getting a new phone.
Everyone appears in agreement that any kind of Linux integration with iTunes is shaky at best. For me at least though the *real* problem is "how do I copy music from Linux onto an iDevice and play it"; iTunes is not a requirement. Here is my solution to that much more tractable problem.

1. Install [foobar2000](https://itunes.apple.com/us/app/foobar2000/id1072807669) on your iDevice (I love fb2k on the desktop - enough to run it in [Wine](https://appdb.winehq.org/objectManager.php?sClass=application&iId=1749), just discovered the app version, hope it's anywhere near as good)
2. Start foobar2000, gear icon in upper right for Tools, [FTP Server](https://wiki.hydrogenaud.io/index.php?title=Foobar2000_Mobile:FTP_Server)
	1. Allow write access = on
	2. Server running = on
3. Connect to the IP address listed using the FTP client of your choice and upload music to `foobar2000 Music Folder` (I suspect I'll use [rclone](https://rclone.org/ftp/) to handle syncing eventually)

After exiting the FTP server foobar2000 will see your music and you are off to the races. And if you don't like foobar2000 as a player I suspect other 3rd party apps could also play from the file system.
