First Engraved iPad
i called apple about this .there remark was they never gave it any thougt! i then ask if i have it done some were esle would it void the war, they said yes. how ever a engraving shop will do it on a nice self stick plate frank
You can always argue against it voiding the warranty since it is only cosmetic, same as taking a sharpie to the back of the iPad.
Bought a couple of the iPod Shuffles in polished stainless and had them engraved.
They did a great job.
I can and do engrave both ipads and ipods - have done many ipods. Use both CO2 and Fiber lasers. Will post pics soon - if you want a quote - email me
