But according to the statement came from his official blog has ended all the rumors regarding to iPhone 4 unlock. In a reply to a comment he clears that he have no iPhone 4 exploit and even he is using iPhone 3GS!

I wish I had an iPhone unlock, the simple BB holes appear closed (my fuzzer comes up blank). In fact, I’m still using my 3GS cause I don’t have one :-/
