Facetime over 3G via an iOS 4.3 Personal Hotspot?

The beta of the iOS 4.3 turns renames “Tethering” to a “Personal hotspot” and enables up to 5 devices to use an iPhones data connection via WiFi, Bluetooth, or USB.

This raises an interesting question relating to Facetime devices (including the soon to be announced and released iPad 2G).

“Can you connect a FaceTime device to an iOS personal hotspot via Wi-Fi and use Facetime over an iPhone 3G connection?”

Unless Apple are going to do something (or have done already) to stop this then it should be perfectly possible. FaceTime works over WiFi and you would after all be connecting to the iPhone via WiFi and we know it’s possible now using a MiFi personal hotspot.

It will be interesting to see what happens next.
