I have heard of ways to get around that but can't ever remember. I would say since you just got it that you need to reset to factory settings.
Turn phone off (pull battery out if you have to)
Once off hold power button and down volume button, this should take you to what is called the hboot screen. Use the volume buttons to move up and down and power button to select. Your looking for the 'Hard reset' or 'factory default' option
