Apple will update iOS to require user permission for apps to access contact data

"Apps that collect or transmit a user's contact data without their prior permission are in violation of our guidelines," Apple spokesman Tom Neumayr said in a statement to AllThingsD. "We’re working to make this even better for our customers, and as we have done with location services, any app wishing to access contact data will require explicit user approval in a future software release."
