As anyone who ones an iPhone can attest, making actual phone calls is not one of the beloved device's strengths. You can blame AT&T's shoddy network, the construction of the phone or the sheer number of iPhone users out there, but dropped calls and poor call quality have long been "features" of Apple's smartphone.

So when Steve Jobs showed off the latest model, which officially launched in the U.S. today, users sounded a note of cautious celebration. The stainless steel band that runs around the phone, explained Jobs, contains its cellular, Wi-Fi and Bluetooth antennas -- a design that was engineered to address those dropped calls and poor reception.
