I have a Blackberry and a Droid. There is an app called "Mr. Number CallBlock" that you can download for free. I use that to block all unwanted calls to my Blackberry and Droid. For my landline, I purchased a Panasonic KX-TG1062M that has a call block feature. Well worth the money. Good luck!
Have received multiple calls. The "offer" is for "stimulus-funded credit card interest rate reductions".
When I indicated that the number is on the Do Not Call registry, he laughed then started on a profanity-laced tirade about how no ______ ______ free list is gonna do s________ to keep them from calling me all they want. That I must be some dumb m_________ f_________ for even thinking it... and it just went on...
