I'm trying to unsync my current iPhone from the current iTunes account to a new iTunes account on the same computer. Right now, all my stuff is linked with my ex-step moms account and I do not want it that way anymore. I've already made my own account, signed into it on my laptop and on my iPhone but when I plug my phone into my laptop it isn't asking to sync with the new account. I know I will lose everything off my phone, that's fine. I just want to be able to use my own account. I'm fine with re downloading all the apps and music.
