Can I filter or block calls with my iPhone? How? With my old droid, there were several apps which did this, but I have not figured out if or how this can be done with my new iPhone.
How do I filter/block calls with my iPhone 4s?
iPhone 4S
You'll need to contact your cellular provider and find out what call blocking features they offer. In the U.S., the official iPhone carriers all offer call blocking services, some free, some for a fee.
