That doesn't really make any sense. A 64GB chip would be the same size as a 32GB chip, unless the just double amount of chips, which would be a pretty stupid way to do it. I've fixed *many* iPhone 4s, and the motherboard takes up maybe 1/2 the size of the phone, probably even less. The biggest piece (aside from the front and back) is the battery, unlike the iPhones before it where the motherboard was the same size as the phone. It basically looks like an "L block" from Tetris, and that's including the rear camera, which is a separate piece on it's own. Point being - if they say that because of having dual radios means they have less space, that's pure horse ****. Remember any features missing from the phone is purely on Apple.
