Not any more... the vulnerability used by Jailbreakme.com was closed four weeks ago. It no longer works. Admit it. Your claim that they are being "exploited every day by the thousands" is not true.
You lied. You stated that ACEs cannot break the OS - it's not a problem. But we have PROOF of ACEs doing it in the past, and that is how current jailbreaking works (ACEs in things other than ACE).
So, if it's not an arbitrary code execution exploit, how do these guys jailbreak the phone? How is an unbreakable OS subject to being cracked within a DAY of release?
You lied, you're wrong, and you REFUSE to admit it.
