i normally do not like to show my caller id... so i go into settings, phone, show my caller id and turn it off. but when i do want to unblock my number with *82, it doesn't work. worked on every other phone i had before. does anyone else have this problem or know if thats how apple intended it to be by design? the opposite will work though, if i turn on showing my caller id, and i wanted to block my number for a particular call, *67 works.
