Dial *228 and reprogram your phone. If it still doesn't work, you may have the same issue that several others did around the time that MR1 came out as the new radio had a different authentication method. For some reason, VZW's system kept the data from the old radio and the phone would appear ok, but couldn't do anything. If it still doesn't work after *228, you'll need to talk to tech support and have them look into it. I'm not sure what exactly it is that they have to clear out, but it's fairly quick on their end to fix the problem.
