There are 6 different types of filters to block unwanted SMS. You have the freedom to choose whether to reject
all incoming messages or to accept messages only from people listed in your phonebook. You can also choose to
block incoming SMS messages from a defined phone number, from a defined prefix number and even messages that
contain a defined phrase.

Just came across this one. If you get an inordinate amount of spam on your mobile, it might be worth having a look at this product from Webgate. Works on Sony P-series, Nokia S60/80, some Motorolas, Panasonics and Samsungs.
