My dad's iPhone 5s is stuck in a iTunes sync
So recently, my dad got a new computer, and installed iTunes and iCloud on it, he plugged in his iPhone hoping for it to work, it did not, I tried figuring it out, I thought turning sync off the old computer would work, spoiler alert, it didn't. So I think it has to do with something with the iTunes sync over wifi. Please help us
Edit : It won't let us add songs, that's what I meant it wouldn't work
