Of course they are!!!!!
I have been an engineer in various communications technologies, including cellular, for over 30 years, so that certainly was not a mystery.
When I have my phone connected to via EDGE or 3G to the cellular network, I simply configure the WiFi in my phone to act as a hot spot to provide an Internet link via WiFi to my tablet which does not have EDGE or 3G capability. That also means I only need one cellular data connection for as many devices as I want to use it with. It is very easy to do, and certainly does not require a great deal of technical knowledge.
