I tried searching on -2 (I know I saw someone ask that question) but the search says my string is too short or too common... So, I can't find it.
My 8700 with the Telstra OS says I have -3 messages. I think I was deleting some spam messages without opening and reading them. Guess it got confused. How do I reset the count?
Thanks! Jumping from topic to topic got me to the solution, just remove the battery, that will clear it... just a FYI for those who have the same problem.
