Is there any way that a previousely submitted SMS (sent mobile to mobile) with a PID of 0(normal mobile sms I think) can be replaced by an sms sent from NowSMS. I know that if the original message is sent with a PID of 41 then if you send another message with the same PID then the first one would be replaced. In this case the first message is not sent with a PID of 41 but we would like to overwrite it. Is this possible in any way?
