iPhone 4 has arrived in iFixit lab and with no surprises, they have taken it down for a full dissection of Apple’s newly released device. The teardown has confirmed that iPhone 4 houses 512MB RAM instead of 256MB found in leaked prototypes, the front glass panel (Retina Display) of the iPhone 4 is constructed of Corning Gorilla Glass to protect it from wear and tear, and there is also a second microphone for voice cancellation just like the one found in Google Nexus One.

The world’s most wanted device is now in the hands of the world’s most foremost tinkerers! The all-new iPhone 4 features upgrades from the 3GS including:

- A redesigned glass & stainless steel body that shaves 3.5 mm off the width and is 3 mm thinner than the 3GS.

- Choice of black or white coloring

- Retina display featuring twice the pixel density of the 3GS

- iOS 4 for multi-tasking

- 5 MP, 720p capturing rear-facing and VGA front-facing cameras

And without any further delay, here is the teardown of iPhone 4 in pictures.

iPhone 4 Teardown (1)“Like the iPhone 3G and 3GS, there are two silver Phillips #00 screws at the bottom of the phone. In a departure from the design of the 3G and 3GS, removing the screws releases the rear case, not the front glass. This design makes replacing the rear panel trivial, but unfortunately means that replacing the front glass will likely be rather challenging”

iPhone 4 Teardown (2) “Removing rear panel gives us a pretty good look at the iPhone 4′s innards. Holy battery! The inside of this thing is dominated by its juice-provider. It’s pretty apparent that real estate was very limited inside the iPhone 4′s 115.2 x 58.6 x 9.3 mm footprint. You can also see the antenna’s pressure contact on the inner side of the rear panel.”

iPhone 4 Teardown (3)“Removing one of the many connectors on the logic board. In our brief usage, we did notice that the phone is considerably warmer on the right side. This makes sense, as the logic board is located entirely along the right side of the phone.”

iPhone 4 the fitting finale..
