Here's a tip. If you're not really skilled at hardware hacks, don't try to hardware unlock your iPhone. If you accidentally touch the wrong thing or screw up, this will happen.

"We were so happy, all the software part was done, so we started opening the iPhone. The antenna cover was a bit tricky but eventually it came off. Then we started to open the metal cover (after taking out the 3 screws) and PUFF, up it went in smoke, I think my collegue must have touched something. It literally went up in black smoke. It was so hot that when I tried to pick it up I burned my fingers. So, this is for sure the most difficult part of the whole process. I don't know what he did, as I had just stepped out of the room to fetch something when I heard a scream...they got such a fright."
Just wait until the software unlock becomes available, and THEN unlock it. Or use the SIM method like we detailed here before. Or ask a buddy that you know has experience with these things. Just for Jesus's (Diaz) sake, don't open it up if you don't know what you're doing.
