How do I get rid of my email accounts on my ipod
I'm assuming by hang you mean that your iPod is frozen and isn't responding to clickwheel or button clicks. If so, you need to restart your iPod. Most iPods restart in similar ways, but the exact method you need to use will depend on which iPod you have.
restart your computer.
To Restart Your Ipod You hold the Menu And Center Button At The Same Time Then You Wait And It Should Turn Off Then the Apple Sign Will Come Up And It Will Be Restarted
When you facetime with another ipod you have to make sure your using the email they logged in to facetime with and that they also have your email. You cant use a phone number. If it still don't work then you probably have the wrong email address and if you don't want to figure it out I would suggest downloading the Skype app. Its pretty much the same thing you just dont have to worry about emails.
make sure you have linked your email account with the ipod
