Hardware Secrets posted a review on the iPhone 3G
It's a cell phone, GPS locator, camera, and video iPod, all in one. It connects to the Internet via cell network or Wi-Fi. It is a complete personal digital assistant that can access email, calendar, and other pertinent information. While it's not the first cell phone to perform these tasks, it's large, clear touch screen, an accelerometer that tracks the position of the device, and a myriad of add-on applications make it unique. Recent price reductions and the faster speed of this new 3G model make it more appealing. So we set out to thoroughly assess the usability and likability of this new device.iPhone 3G Review
