pySMS is widely popular among Symbian users. pySMS is an ingenious SMS bombing app designed for s60v3 Nokia handsets that allows you to "flood" to any mobile number. pySMS is easy to use; just specify the quantity of SMS to be sent and then choose spammer's mobile number. You can then "bomb" that nasty marketing guy who keeps on sending spam text messages.
