Apple has announced that it will change the policy on apps and will require the app developers to get user permission before grabbing data off the device. That means that an app like Twitter has to get your permission before it looks through your address book to find out which of your friends is also on Twitter. The rules were changed because some apps were exporting the data to servers, where the info could remain for months. Also, the U.S. Senate has introduced a cybersecurity bill aimed at protecting computer networks in the U.S. from attack.
