These leaks are likely real, but wondering about the advantage of creating fakes...this calls for a face palm.
Have you noticed any litigation Apple might have been involved in lately? Like maybe the one asking for over 2 billion in damages because they say Samsung copied their designs? Apple is upset enough over copying of already released models, hence their ultra paranoid stance on pre-release secrecy.
Are you trying to say that Apple would create fake leaks so that Samsung can't copy it? The phone is released in 4 weeks, man. If Samsung wants to copy it, they can wait 4 weeks.
