You guys should listen to the 200th Engadget Podcast. Joshua Topolsky made a good point that they were using an iPhone 4 shell that didn't have any of the components in it. He thinks it would of probably been a different story if it was a real iPhone with everything put in place.

[Merged] iPhone 4 Glass Body, Durability, and Drop Test Results

Tempered glass does not break in one piece, but rather thousands of glass chunks.
Anyways, from Apple's video, it appears the glass is laminated to the LCD screen. That is, they're now one solid unit. This may make repair extremely difficult.
I think many people misunderstood this..
The glass is not laminated to the screen itself...it is laminated to the touch digitizer...and placed right over the LCD.
They can't laminate the actual LCD to the glass or it would not be easily replaceable and affordable. Apple is expensive but not stupid.
If you look at all of the fix places that have gotten parts for the new iPhone..the screen is separate from the glass...just like on the current phone,..but there is no airspace between the glass and LCD now.
They don't even have the iPad case ready yet, and that came out 2.5 months ago. No way I'd wait over 3 months for a case after seeing this.
...or force=(mass)(acceleration), and with all the guts included, the heavier object would strike the ground with MORE force and POP on the 1st try!
You are trusting a company that doesn't even show the glass display of the iPhone correctly when you view it on their site. Sorry but this won't be settled until it's released and somebody takes a pick axe to it.
And those displays may say apple on them but it doesn't make it OEM. could be knock offs.

Pretty sure I was right with the iPhone 4 using gorilla glass and this ifixyouri test was a complete farce. They had to have had knock off glass front.....AND do we notice that ifixyouri never followed up with a video? Hmmmmm, looks like somebody was looking to make a quick buck.
Allllllright...let's squash this once and for all. We're not in it to make a quick buck. We were informing the public of what was going on. The glass was real. We waited to make a video until we had the iPhone 4, shipped from Apple. Well guess what, we got it today, and as promised, we drop tested it again, with a video camera. The first drop test was NOT fake. Nor is this one. We video taped it. Glass + hard surface does not mix. Period, end of story.
I can't embed video in the forum, i'll post the pics, the video is on our blog and up on youtube, unedited. It is a real iPhone 4, straight from Apple. Enjoy

Mechanical Properties of CG2317
Young's Modulus: 73.3+/-2.6 GPa
Micro hardness (Vickers): 701kg/mm2
Fracture toughness: 0.7 MPa*sqrt(m)
2317 features a chemical strengthening through usage of ion exchange wherein the ions of the silicate and the network modifier (sodium) undergo ion exchange which results in a compression layer.
One of the tricks with Gorilla Glass is that it suffers microcracks (cracks with aspect ratios on the micron scale) which are not visible to the human eye and do not cause conductivity or strength problems. Most glasses corrode in air, but Gorilla Glass will arrest the cracks at small intervals to stavex off full failure for some time.

What a lot of people don't seem to realize is that on military helicopters and high speed trains, the glass is several inches thick.
I'm sure the iphone 4 could be super sturdy if they made the screen several inches thick with this stuff.

I stand corrected. Thank you for sacrificing your iPhone for a test like this.
I'm more shocked at the glass scratching rather than it breaking. Any idiot knows glass breaks no matter how 'hard' it is.
I wanna see someone show how much abuse it needs to really scratch it. Also, confirm if the treatment on the glass differs from front to back.

Thank you so much ifixit.
I think you saved a lot of people a lot of future grief by showing them now once and for all that the phone isn't indestructable, and they should indeed take good care of it.
I will go to your site for all my iphone fixing needs.
But importantly, so do we now know for a fact whether or not the iPhone 4 does indeed use gorilla glass?

Yes, the glass edge is not directly exposed. A very thin hard plastic or metal wraps around it. It looks like its the same thing in the antenna gap.
