I’ve been loading my own music into my I devices since the iphone3GS. I imported my CD rips into iTunes on my desktop and it synced to the I devices.
You’re operating under misinformation.
Myself, I have a cheap phone (not a smart phone) that I put music on. It is really simple. Plug in a USB cable and copy the songs over from whatever. The cheap phone just looks like a generic external drive to other devices. That is about a complex as I care to deal with, LOL.
Right. But! You have to put all your music in one library. You can’t synch music from two different computers. It’s a pain.
