The story of how they got their phone is even more interesting than what they found inside. Kyle was all set to hop a flight to Japan and wait in line at the Ginza Apple Store when pre-ordered iPhones started arriving early, saving him the trip. He and the rest of the team got right to work.
First of all, let us give kudos to the iFixit team for a set of very well-done photos. I'd love to get a look at their studio setup some day. Highlights of the teardown include how easily accessible the battery is. By removing the two bottom screws, iFixit notes, the rear glass pops right off revealing the battery. It's not soldered into place and very easy to remove.
They also confirmed that the iPhone 4 does indeed have 512MB or RAM, a 1 GHz ARM Cortex A8 core processor (just like the iPad) and UMTS, GSM, GPS, Wi-Fi, and Bluetooth antennas built into the stainless steel inner frame.
It's also noteworthy that the LCD panel is securely glued to the glass and digitizer. If you break the glass, you'll have to replace the glass, digitizer, and LCD as a single assembly. So, you know. Don't.
There's a lot more and we encourage you to check out. Great work as usual, iFixit.
