    Is there actually a hardware change in the much anticipated 3G phones or will those with current phones be able to upgrade through a firmware change?

    I believe 3G uses WiFi instead of EDGE for internet, or something along the line.

    3G compatible iPhone might have extra camera in the front for Video Calling.

    No, it doesn't use WiFi. The iPhone already has WiFi. It uses HSDPA, which is ATT's 3G protocol. It offers DSL-like data transfer. This includes voice.

    3G is a combination of hardware and software. Essentially, you need the hardware, so no firmware update would do it (unless you could plug in a 3G adapter to your phone, but that doesn't seem likely. Then again, the contraption is useless without (proprietary) software that interprets the data.

    As an electronic engineer, I can authoritatively say it's a hardware change. But most people know that already.

    Maybe one day we will have entirely software-based radios. It's not going to happen any time soon, though: new standards typically mean higher data rates, and software can't keep up with all the processing that can be done in hardware.
