This is my opinion:
This is probably fake.
he wrote these things in a thread on how he obtained the 3.72 keys:
Exploit works out and copys keys to an external USB storage device (was a bit horrible but its ok), it actually copies it in the .bin format... so you open it with a hex and its fine,also it gives names so you wont get confused
Now, if he found a way to get some "keys" from the PS3, he should know that he can't see them or found them on a simple dump file. they need to be calculated.
so which is the problem
? two random variables. without them you can't do anything. they can't be obtained.
Another thing is Exploit is actually HARDWARE hole... so it means ITS NON PATCHABLE,like Xbox 360 glitch.. or some.
any hardware exploit is patchable by software (an example was the old exploit)
