I do believe the US and UK governments have access to cell phone traffic (Echelon), so part of this is no surprise.

But what I don't necessarily believe is that the government of India is in on it. Or that they are intercepting memos written by the United States about some confidential stuff. I feel this whole thing is a hoax and not real.

Has this been confirmed by anyone? I wouldn't necessarily trust some "hacked memo" posted to Pastebin. Also, the title bothers me. Memos are leaked, not hacked.
