some interesting anti-telemarketer software for your mobile phones

trying to compile some good software to fend off these nonsense companies who just won't take NO for an answer -- NO MEANS NO!

anybody else tried before? comments please

CALL FILTER

1. caller gets through one ring and gets terminated automatically (may not be "good enough" for those who do not even wish to have the call put through)
2. user interface is pretty easy to setup
3. best of all - FREE =)

note - if you experience "certificate expired" during installation, simply change your phone's date settings to 2007 (dd/mm no need to change), try installing again (it should work), then change phone date back to current date.

BLACKBALLER

1. caller gets through one ring and gets terminated automatically (may not be "good enough" for those who do not even wish to have the call put through)
2. user interface is also easy to setup
3. comes with 14 days trial after you download (purchase price US$13.50)

HANDY BLACKLIST

1. not yet tried, screenshots available ... looks to be similar to the above 2 in terms of general use and function
