Has anyone had their iphone 4 glass color changed?

I'm wanting to have the glass in my phone changed to a new color by a store called Ifix & Repair. Has anyone ever had this done before by anyone? Did the phone still work good after you had the glass changed?

No it won't work

Oh yes, I changed mine, and it still works the way it worked before

I haven't however my friend had his changed to a line green color. He managed to do it by himself and there was no performance change whatsoever. If you're using an actual company there's maybe a 2% chance of something negative I would guess.
