You would have to ask your carrier, but most carriers just require a data plan, and you can use whatever connection type they offer.

Typically, at least in the U.S., they cost the same. It's entirely up to your cellular carrier, though.
To be sure, you might want to contact them. Here's how:
Typically here in the U.S. 3G would be used preferably, and EDGE only if 3G were not available.

As a rule, there is no cost difference. 3G will just allow you to use your data allowance more quickly.
In many places, including the US, carriers are shutting down their EDGE networks. AT&T is one. As that happens, you won't even be able to use voice services, much less data if you're not on 3G.
