4.3 at&t wifi hotspot

On the mytouch 4G I could leave wifi enabled/connected and still use the hotspot. The hotspot pulled through the 3g/4g connection. I guess it depends on how Apple sets it up.

The Wi-Fi hardware in the iPhone can only connect to a wireless network or create its own network.

It can't do both at the same time.

I think there is some confusion somewhere, the iPhone gets data from its 3G connection then shares it to other devices via WiFi. Which is the same way that all phones with WiFi tethering work. If you are talking about cable tethering or bluetooth tethering then you should still be able to connect to a different wifi network at the same time.

But if your iPhone is already connected to a separate Wifi network why wouldn't you just connect your laptop to that same wifi network and not use the phone's (probably) slower 3G data?

I don't think that's possible, because you can't really configure the Hotspot feature.

It only supports two options:

USB + Wi-Fi (when Bluetooth is switched OFF)
USB + Bluetooth + Wi-Fi

What you say is theoretically possible, but Apple doesn't allow it.

Someone mentioned the possibility of leaving the "Personal Hotspot" feature ON all of the time. When the feature is switched ON, the iPhone cannot connect to a Wi-Fi network even if nobody is actually connected to the hotspot.

This makes leaving "Personal Hotspot" on all of the time impractical.
