As I wrote in my July 15 review of the iPhone 3G, the latest version of Apple’s handheld computer, the best way to judge a device like this is to use it for a while. It’s been more than a month since I bought my iPhone 3G, switching from my trusty Samsung BlackJack. After more than 30 days of relying on it as a phone, e-mail reader, Web-surfing platform, information retriever and time-killer, I’ve found it to be both remarkable and maddening. It really is a breakthrough product.
