iPhone 4 teardown

The guys at iFixit have done it again, this time bringing us the first legal a teardown of the Apple iPhone 4.

Some highlights from the teardown:

Removing the back cover is a snap - undo two Phillips #00 screws and push the back up with thumbs.
The 3.7V 1420 mAh Li-Polymer battery has a massive 115.2 x 58.6 x 9.3 mm footprint.

The dual purpose stainless steel inner frame/antenna assembly addresses possibly the two biggest flaws concerning previous iterations of the iPhone: continuous dropped calls and lack of reception.
The phone uses the 1 GHz ARM Cortex A8 core.
We get confirmation that this handset features 512MB of RAM.
The iPhone 4 sports two cameras -- a 1.3 MP front-facer, and a 5 MP on the back. Both are located on their own independent boards, making it possible to physically remove the cameras without damaging the phone.
Logic board goodness: - Skyworks SKY77542 Tx–Rx iPAC™ FEM for Dual-Band GSM/GPRS: 880–915 MHz and 1710–1785 MHz bands. - Skyworks SKY77541 GSM/GRPS Front End Module - STMicro STM33DH 3-axis accelerometer - TriQuint TQM676091 - The AGD1 is the new 3 axis gyroscope that we believe is designed and manufactured by ST Micro for Apple. The package marks on this device do not appear to be the currently available commercial part, L3G4200D. The commercial version of this gyroscope is yet to be released — Apple got first dibs on it.
- Samsung K9PFG08 flash memory - Cirrus Logic 338S0589 audio codec (Apple branded). This is the same part as in the iPad. - AKM8975 - newest magnetic sensor that promises to improve the performance over the prior generation. - Texas Instruments 343S0499 Touch Screen Controller - 36MY1EE Numonyx NOR and mobile DDR
Wi-Fi, Bluetooth, and GPS are all provided by Broadcom and located beneath EMI shields on the front side of the board. - Broadcom BCM4329FKUBG 802.11n with Bluetooth 2.1 + EDR and FM receiver. - Broadcom BCM4750IUB8 single-chip GPS receiver.
The front glass panel of the iPhone is constructed of Corning Gorilla Glass, a chemically strengthened alkali-aluminosilicate thin sheet glass that is reported to be 20 times stiffer and 30 times harder than plastic.
The LCD panel is glued to the glass and digitizer. This means that if you break the glass, you'll have to replace the glass, digitizer, and LCD as a single assembly.
