Apple iPhone 4 (CDMA)
I have the droid Incredible..I can set a number to go straight to voice mail when they call..Will not ring on my phone..Just shows I missed a call..Can it be done on the Iphone 4??
You can also accomlish this via Google Voice I believe. That is where you get a Google Voice number and tell whomever you want to block to call that number instead.
