New York, Feb 21 : During his first days in office, US President Barack Obama insisted on keeping his BlackBerry. But if you think that his firmness has anything to do with keeping in touch with pals or work on fly, you're absolutely wrong.

Apparently, the American leader is addicted to mobile game BrickBreaker.

"He plays to unwind," The New York Daily News quoted a source, as saying.

"Every night before bed, he gives it a few minutes," the source added.

Despite warnings from his advisers, the president has insisted on keeping his beloved PDA, which has specially designed superencrypting security software.

Obama''s super-secure BlackBerry is like a "holy grail" for hackers.

And, according to the world''s most famous hacker, the equipment can be hacked.

"It'' a long shot, but it''s possible," Kevin Mitnick recently revealed.

"You''d probably need to be pretty sophisticated, but there''s people out there who are," he added. (ANI)
