Root What does this mean?

When I hold the Power and Up volume on my phone, I get the Android Robo Logo but it is the little Green Bot lying down on his back with the front of the chest area open and a Big Red Triangle with a "!" in the middle and that is all. Nothing happens after that and I end up having to do a Battery Pull to start all over.

Does this mean that I am locked out of being to get to the Boot Menu?

Well I found out the answer to my question. AT&T Has locked all their phones from any Bootloader Access.
