How can I block incoming SMS from certain senders? What is a good app for blocking incoming SMS? I want it to be easy and able to add numbers from contacts and not require to many privileges (probably only some storage and intercepting SMS).
'Call &amp; SMS Filter'. I've not used it but description matches what you are after &amp; very good comments.
I believe Handcent SMS also has block options.

Required privileges on both are greater than your preference though.
