Custom titanium shell gives the iPhone 3Gs its heft back

The first generation iPhone’s metallic underbelly was undeniably magnetic to objects like the sharpest ridges of house keys, and in that sense, the current iPhone’s backing is an improvement: the plastic just doesn’t pick up scratches like the metal iPhone backplate used to.

Still, there’s something ghetto about a plastic iPhone, isn’t there? It just doesn’t feel like an Apple product anymore unless it has been hewed out of a piece of aluminum. Martin Schrotz seems to have felt the same way, because he decided to ditch the plastic backplate of his cherished iPhone 3Gs and replace it with a custom titanium body he forged himself.

The process wasn’t without its pitfalls. “I had the original cover measured digitally, and I then started to draw the new cover in CAD. It’s made out of a special titanium alloy that is RF transparent. I had tried aluminum but that was a complete disaster.”

The Apple logo is a bit big for my taste, but otherwise, I’m jealous: my first-generation iPhone has always felt firmer and more substantial in my hand than my girlfriend’s second-gen iPod Touch, but barring Apple restoring the metal-backed option to their iPhone line, this is about the only way in town to marry the performance improvements of Apple’s later handsets with the heft of their first design.

    I bet they aren’t cheap to make with all that titanium.

  • Keith

    I want this. if you sell them on etsy I will totally buy one…

  • http://cesargraphics.com Cesar

    would purchase one as well but with smaller apple . . . .

    This is really cool.

    I reckon that guy could make a business out of this, seeing as pretty much nobody does metal iphone cases/enclosures.

    I also think the apple is a little too big, but i would happily buy one of these if they could reduce the size of the Apple a tad.

    Looks very cool.

    Wow, that really does look brill. True Apple logo is a bit big but to me it now looks like the iPhone 4G. The iPhone, but a slick unibody design.

    There’s no such thing as rf transparent Ti alloy. Or a rf transparent metal or alloy of any kind. The guy is pulling your leg. The very fundamental property of conductivity precludes a material being rf transparent. The free carriers present in conductive materials all absorb rf photons. He could use a wide bandgap semiconductor that contains Ti, such as TiN or TiO2, but you would never confuse those with metals. If he’s really done this, the only source of communication must be through the front panel, through all the electronics and screen, which with it’s capacitive grid, is pretty rf absorbing as well.

    John, please give me your professional transliteration for “something ghetto about a plastic iPhone”?

  • Poppa

    It looks good, but with a smaller glowing Apple logo like the Macbooks it would be better.

    I’ve been using the original iPhone since 2007 (still no scratches, never used a case on it) and from what I’ve seen the plastic on the 3G and 3GS is definitely more “magnetic” to scratches compared to the aluminum backing of the original.

    Umm… that would be “hewn”.
