I don't have live wallpaper add on installed and I still lose my APNs when I restore my apps with TiBu. Right now I am restoring 1 or 2 apps at a time and rebooting to see of I lose my APNs. Then that way I will be able to know what app is the one that is killing my APN.
I'm running 2.5ee

Well, I usually start out by downloading SU elite and updating my binary before restoring, not sure if everyone does that, if you haven't done that, try it out, see if that helps, I've never had any problems with the APNs.
