LOL until you scratch the "Hard to scratch" glass the first day you have the Iphone ( My 3g)
Ever since I have a Case and Screen protector and cannot imagine without one.
My wife throws her phone in the purse and it does get scratched so she has one
Iphone4 without bumper? Hmm
I have a sleek case easy to take out of
I feel little difference between the protector and glass its good, no bubbles
$0.99 from Ebay
Up to you some claim never ever a scratch or a nick, yet so many phones resold on ebay have them, must be a number that do then.
