Same exact thing happened to me last Friday when I got the phone, I was locked out of the phone all day during a conference, couldn't do anything except stare at it and see the notification LED blink and read little parts of texts/e-mails I was getting (really frustrating

). Went to a Verizon store after the conference was over, they played with it for what seemed like forever, we changed my gmail password numerous times, and they finally gave me a new phone after 2 1/2 hours... needless to say, I haven't set a lock pattern for my new phone
