The intrepid tinkerers at iFixIt now bring us what they refer to as "the first legal teardown of the iPhone 4." And being first wasn't easy. They first went to the other side of the earth to obtain an iPhone 4 before anyone else in the States. As they explained in an email: "[CEO] Kyle [Wiens] flew to Japan, expecting to take …
