Just unlocked my iPhone 4 on 5.1

It worked!

My 3GS just died Thursday. I grabbed an iPhone 4 from a friend and spent the weekend struggling with unlocking it. It was on 4.2.1 and baseband 03.10.01
I was searching for a Gevey sim.
Then this came out last night. Done.

How long was the process?  Did it work on the first try?

it took about 3 tries, as i didn't understand the process completely the first time.
It seems the SAM unlock has been blocked by Apple now, but i got it done when it was working.
