Yep I do too. I think it's because the SO system doesn't support short code SMS messages. I had 1 go through from Yahoo and then I got another SMS on the phone saying I had to reply to a short code to verify the phone (or something like that).

"Your message to XXXXX could not be delivered because their Mobile Phone cannot receive text messages at this time."

Does anybody else have this problem?
