Differences Between The AT&T and Verizon iPhones

The consensus amongst the Verizon iPhone 4 reviews is that there is little functional difference between the Verizon and AT&T versions of the iPhone, beyond the portable hotspot capabilities that were widely known. Of course, the main difference between the two phones is that they have different radios in them to support the different wireless technologies that AT&T and Verizon use. It turns out that because of the different wireless technologies, there are some subtle differences in the phone settings between the two versions of the iPhone.
