Union IT minister Ashwini Vaishnaw has announced that an enquiry has already been ordered into the phone hacking allegations made by some opposition leaders. He requested those who have received the Apple alert message to cooperate with the probe. "The Apple has clarified that the advisory was issued in 150 countries. The alert is vague. Apple claims that its encryption system cannot be hacked and it has also issued a clarification that negates opposition allegations," the Union minister said.
