Apple iPhone 4 Innards Exposed, Celebrated by iFixit

Apple iPhone 4
"The world’s most wanted device is now in the hands of the world’s foremost tinkerers!" iFixit wrote on it its site, where it displayed photos of the "tinkered with" iApple iPhone 4.
Different Design
The repair site calls the design of the iPhone 4 a "drastic departure" from the aluminum- and plastic-based designs of its predecessors. It also noted that the rugged stainless steel bezels around the phone act as both structural supports and antennas to aid reception.
Better Battery Life
Increased battery life is a promised new feature with the iPhone 4. At left, iFixit engineers show off the Li-Polymer battery they pulled out—and which is expected to offer 7 hours of talk time over 3G, or up to 14 hours on AT&T’s 2G network.
Display
The iPhone 4 appears to be all smoke and mirrors, as the display is separated from the frame. iFixit notes that the iPhone’s display panel is Corning Gorilla Glass, which is "20 times stiffer and 30 times harder than plastic." It’s also highly resistant to wear.
Video Calls
At left, a member of the iFixit team pops out the larger of the iPhone 4’s two cameras, the 5-megapixel model. The inclusion of a 1.3-megapixel front-facing camera is meant to facilitate video calls.
Logic Board
Ignoring the warning signs, iFixit sets to work removing a connector for the logic board. iFixit
Valuable Real Estate
And the logic board is out. The piece’s unusual shape and small size, notes the site, speaks to how valuable real estate is inside the slimmed-down iPhone 4.
Antennas
The UMTS, GSM, GPS, WiFi and Bluetooth antennas are integrated inside a stainless steel frame—a move that iFixit writes "can only be described as a work of genius." It adds that Apple has also "tuned the phone" to defer to the least-congested network band, which should help with service issues on the AT&T network.
A4 Processor
At left is Apple’s A4 processor, which was included in the iPad but is said to be more powerful in the iPhone 4, where it’s paired with multitasking capabilities. To the left of the A4 is the 3-axis gyroscope, which reportedly isn’t commercially available yet. "Apple got dibs on it," wrote iFixit.
Front-Facing Camera
Adios to the front-facing VGA camera.
Various Parts
Don’t try this at home: At left, a final shot of the disemboweled Apple iPhone 4. The phone officially goes on sale June 24 at Apple, Best Buy, Radio Shack, Wal-Mart and AT&T locations and is of course for now exclusively available in the U.S. on the AT&T network.

Repair site iFixit, along with Chipworks, released a teardown of the Apple iPhone 4 June 23, a day before the device officially goes on sale. The site says it worked hard to get a hold of the iPhone 4—and wasn’t disappointed once it did, marveling at Apple’s treatment of the phone’s multiple antennas, its Gorilla Glass front display and the gyroscope Apple scooped up before anyone else. Other good news is that the iPhone 4 appears to be "tuned" to defer to the least-congested network band available to it—which is good news for AT&T and its customers in highly populated areas.
