It is highly probable that rooting and/or flashing your phone has interfered with its ability to accept OTA provisioning for new phone settings. The symptom you are describing is similar to launch day difficulties I was having because of the massive amout on provisioning they were doing... they were overloaded and the phones were taking a long time to complete. In your case, the issue is probably that your phone is unable to accept the OTA provisioning at all.

Go to settings, system updates, and select Update Profile. If your phone still doesnt work, reflash to stock and do Update Profile again.

This is why I don't mess with custom ROMs. They were a necessity on WinMo... but Droid rocks on its own.
