I went to get new headphones at the genius bar and they asked to see my phone to check the serial #. I completely forgot the phone was jail-broken. The genious said "I'll pretend I didn't see "Installer" and "Cydia". He also ran a diagnostics software that again let him know the phone was currently jail-broken. He let me know that next time I should restore my phone because technically this voids the warranty etc. I am lucky. Awesome genius/tech. New headphones. Whew.
