Update: David Pogue of the New York Times has also turned in a kinda-sorta review of the iPhone 3G, though it reads more like an overview of its features than a honest-to-goodness critique. He also makes passing reference to the GPS antenna being "too small" to function as a proper GPS, which makes roughly zero sense to us. Feel free to figure it out on your own.
Update 2: Can't forget Ed Baig of USA Today, who says the new model is "worth the wait" (not to say we have any option at this point anyway, seeing how hard it is to find an original anywhere). He seemed to have trouble picking up 3G service in some locations, though it's not clear whether that can be chalked up to technical issues with the handset or a lack of coverage where he was testing. Like the others, Baig discovered a noticeable improvement in audio quality and a noticeable hit in battery life when hooked up to the 3G network. Gotta pay to play, we guess.
