its a great idea to personalise your phone

you could very lightly etch it or stratch it in and fill it with transparent adheasive so it would still be strong but noticeable unless you want that glitter.

put your home phone number not your address

Doesn't matter which type of glass it is. mostly they are some kind of borosilicate glass with some additions and protecting layers.
Most important thing to know is which wavelength your laser is emitting and if this wavelength is absorbed by the material of interest. As we all know, glass is usually transparent to visible light (range of 400-800 nm wavelength). So if your laser uses also visible ligth, your etching wont be successfull. Etching with a laser only works, if the light of laser gets absorbed. Thus the energy of the light gets transformed to heat and by that laser ablation works.
look at that graphic for a special borosilicate glass (pyrex)
reading this, your laser should be far in the uv light (lambda < 200 nm) or far in the infrared (lambda > 3500 nm)
Good luck!

Edit: I just had a quick search on the gorilla glass. here is some kind of datasheet:
Here you can also find a transmission spectrum (here it is for gorilla glass 3, but should be valid for gorilla glass 2, too). Looks similar to the one behind the link I posted. so the conclusion remains.

Keep in mind: If you etch any personal information onto it, the resale value plummets, maybe even becomes nonexistent.

Re: [Q] Laser etching the glass back
I've laser engraved some iPhone 4 backs which I think are gorilla glass. Didn't come out as well as engraving normal glass, so I wouldn't try any intricate details.

The glass seems very thin... to me it looks much thinner than the glass of the iPhone 4.

I wouldn't try my luck~ If you are experienced and know your stuff go ahead though.
