Wow, electronic devices don't like being dropped from a substantial height.
Fancy that.
Is there a case that protects from stupidity?
The existence of bumpers just proves that Apple knew about the iPhone antenna issues before they released the iPhone 4.

Unfortunately, there have been no comparison tests with more traditional cases, so we're not yet sure how much better protection a full case actually offers.
The existence of bumpers just proves that Apple knew about the iPhone antenna issues before they released the iPhone 4. It provides just enough distance from one's hands and the antenna. What a coincidence. Apple now has a PR nightmare on their hands. And yet - the iPhone 4 still sells like crazy. Amazing.
AFAIK, Metal elements only become transparent under high pressure. (Or if you see in XRays with the power in the order of Gigawatts)

There is Indium Tin Oxide, but its not extremely suitable for such a thing.
Aluminum ceramics (aluminum oxynitride) are being looked at for bullet-proof glass replacements. They can take a .50 round, but cost $10-$15 / square inch. http://science.howstuffworks.com/transparent-aluminum-armor4.htm
Gorilla glass (which is used by the iPhone) is said (by Apple) to be similar to sapphire glass (a marketing term for you want here.
Perspex is better if you want shatter resistance. Often, it's hard things (like glass) that are good at resisting scratches, but break if you drop them.
This test demonstrates that the bumper offers nil protection when dropped at a normal holding height on concrete.
The glass is reasonably scratch resistant and also very flexible (as shown in Apple's iPhone 4 video). The problem is that the flexibility is absolutely useless for this particular design, since there is zero flexing allowance for energy absorption once the glass has been glued to a hard surface. On impact the glass is caught between a rock (the ground) and a hard place (the phone), so to speak.![]()
Even though it was encased in an Apple bumper, the glass is not as strong as Apple says it is.
Well the bumper actually offers 100% protection to the area it covers - the softer aluminium band. How the hell is it supposed to protect what it doesn't even cover?
I don't know, perhaps by protecting the back and sides the same way? God knows the aluminum backing is so much more important than the glass front... How about giving the bumper a small amount of space between the glass and raised border (above the glass) so it's not flush with the concrete.
Funny, I've never seen a sapphire shatter on contact with concrete...
