Hi everyone!
Hehehe, mr. Blend went crazy with his demostration how the rear encasing of iPhone 3g,
I’d like to try it myself and find out what it makes this material sort of unbreakable, I am still wandering why AT&T went so cheap and girly with the new desing such as it’s core itself and the back desing looks to femenine even though there are no pink color as far as I’ve known but, it is some kinda funky rear desing in otherwards.
Many of my friends that are actually using this iPhone upgrade (3G) have lots of complains may be not because of the pricy service as everybody already know. If you compare with 2G which was the first generation of iphone , it has a unique rear desing that can be put on flat surfaces and tapping to it without shaking sideways.
Why didn’t the bunch of engineers think more wisely while upgrading this cellphone masterpiece.
Please Mr. Steve Jobs take possible considerations for the public.
We all want to be heard so, please go back to the old friendly tapping desing thank you.

no offense but you have it all wrong — the piece that remains is a metal insert into the material that makes up the back casing — providing for a metalic apple emblem viewable from behind and a foundation for mounting electronics — it is the smaller shape because of the curvature of the back. this piece and the bezel survive because they are both metal and not other materials. what you are seeing is not space age material…

Somehow I don’t see anyone making calls with that Apple-logo.

Well, it depends on how you define “stronger.”

You can measure “strength” as a function of tensile strength (Young’s modulus), shearing strength (bulk modulus), impact strength, etc.

I would argue that ceramics offer greater shear and tensile strength over steel. I’m not sure about ceramic’s impact strength qualities, but perhaps that’s why Apple’s patent application outlined a Zirconia/Yttrium hybrid ceramic.

Ceramic is not stronger than steel or even aluminum. Its main advantage in an application like this would be its hardness if in fact it makes up part or all of the shell. Ceramic is in fact fragile. It’s incredibly hard, and almost impossible to scratch. Ceramic blades are the only ones that can easily cut kevlar, spectrashield and zylon. Ceramic is also used in hard body armor to defeat armor piercing rounds. While it will shatter after being hit, it will blunt and break AP rounds so the armor behind it can catch the round.

Apple did actually say that the new material would be scratch-resistant. And, my iPhone 3G is so far scratch-free.

thats cool if its not plastic, it wouldn’t scratch so easy then!
