I'm trying to figure out whether I'll be able to use the 3G capability of the iPad. I live in a small town on the coast of Maine and nobody I know uses AT&T around here. If I'm reading the AT&T coverage viewer correctly, my house sits in a spot that has EDGE coverage. In fact the whole coast in this area seems to have this level of coverage (which breaks up pretty drastically as one moves inland), leading me to surmise that AT&T must have a tower on an offshore island somewhere. We've got a million of those. Does this mean that I can use the 3G capability to get online, but at lower data rates? Or that I won't be able to get online at all? Thanks. I'm totally new at this.
