Phone stuck at att screen

[20blks]

I got an ota update today. After I selected to install the update, the phone attempted to reboot and it never gets past the att logo. I can't get into recovery mode. It just keeps trying to reboot. I can't get to a service center until tomorrow sometime. Any assistance would be greatly appreciated

Bring it to the nearest Device Support Center (ask at your local store). Ask them if they can reflash just the update. (You don't want the whole new ROM flashed, that will remove all changes you've made to the phone since you got it - you want just the last update, the one you just got, reflashed.)
