I got the "there's an OS update available" message on my VZW Classic this morning and went through the process. But now it appears to be stuck. Calls and new message notifications are arriving but the screen won't progress past the red VZW splash screen. I can't send messages (or even read the ones that are arriving). Help! What can I do? I've already done 1 restart in addition to the restart it did itself as part of the upgrade.
