So getting an iPod Touch soon and just saw on the App Store "Talking Carl" which looks so cool. But I know that you need the headphones plugged in to use it. But when "Carl" talks back. Will it play through the headphones or the in-built speaker? If it does through the headphones. Can I make it play through the speaker so everyone can hear it? Cause I want to use it at school for a laugh but it won't be as fun with everyone taking turns using the headphones.
