I called AT&T to inquire about a USBConnect card and the rep said "Oh I happened to notice you have an iPhone. You won't need anything like the USBConnect card to use AT&T's internet, just use your iPhone and it'll share its connection with your PC/Mac." . I thought it was weird. So I said "Really ma'am, can you explain how that works?" She said "Yes well you just get the USB cable, and plug one end to your iPhone and the other to your computer. Your computer will instantly recognize it and you can start using your iPhone's internet on your computer, provided you have a USB port." What is she talking about?
