I'm not sure if this is the place to ask this, but I want to engrave a design on the back of my iPhone and was wondering if anyone else has done this. I've found information about the specific laser settings required to engrave the original iPhone but I've found nothing about the iPhone 3G or 3G S.
If I can't find that information I was wondering if someone has a dead iPhone 3G or 3G S with an in tact back shell I could have to test the strength (I just want to engrave the shell, not the circuits below it :D). I bought a replacement shell from a site online but it is clearly a different material making it rather useless for testing.
Thanks for the help.
