I'm moving to verizon in a month or two and I'm deciding between the Droid X, and the Droid 2.... I'm leaning towards the X but this is what confuses me.
Droid 2 has just 3g.
Droid X has GSM 850/900/1800/1900 3G HSDPA 850/1900/2100
I know what 3G is, what I don't know is what all the other stuff is. I realize they are other networks, but how will this benefit me? I am most likely not going to be outside of the US, and when I do I'll use skype

So living in America, will the other networks really benefit me? Like if there is no 3G and no edge I guess I can be on one of the other networks, where as with the other phone I won't have reception, or am I totally off?
Please help.
