What it sounds like is that the data connection during the download of the update was intermittent and in the process corrupted part of the file. I'm surprised it didn't just throw and error and refuse to update, but in any case, this is where you are now.
When they flash the old firmware what they are going to do is completely remove the failed system and then run the official update from a known good file. You will lose any apps and text messages and email stored only on the phone. Pictures are another matter. It may be that the routine AT&T uses to flash misbehaving phones will reformat every bit of memory, including SD storage which will delete everything. However, there is a possibility it will lead the storage intact and only reinstall the system. In either case you will need to re-setup your phone from scratch.
If the information is useful, Like the post, if the person was helpful, Thank the member.
