The earlier models of iPhone were produced when 4G was not out yet and so, obviously, they cannot be compatible with it. However, since 4G has been released, you can expect the newer models to be 4G compatible, especially since the current iPad is capable of using some 4G connections.

From what I gathered by research no it isn't. It's a more powerful 3g but not as good as an actual 4g capable device
The Nexus S is a 4G capable phone. This means that it is capable of running on your carriers 4G network. However, it can also fall back and run on the 3g or 2g network as well, so it supports them all!!

Just the way they've been manufactured. Some of the older phones are simply not capable of using 4G - because either the components they're made of can't work with 4G protocol, or the software can't process 4G operations.
Not yet, but Rogers has been testing 4G LTE in the Ottawa which may mean that Ottawa will have 4G in the near future.

Do you mean "What is the purpose of 4g"? Learn English. I presume you are referring to 4th generation mobile networks. They are faster than 3G (and Edge and everything else). So if your phone is 4G-enabled and you are on a 4G network, you will get much faster internet, as well as clearer and more reliable phone calls.
