You can use APN Backup to backup the APN info to your SD card if you don't feel like typing in manually (as opposed to typing it in telekinetically I suppose).
Obviously you will have to reinstall APN BAckup to get them back. Of course maybe y'all should use something like Astro File Manager to back up your apps to SD card as well.
I wish they would make My Backup free!
