As expected, the tool-minded folks at iFixit have torn down an iPhone 4 and posted its inner workings for all to see. There are plenty of juicy high-res photos and details here.
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.
