Lets say I get a 3G iPhone. I then realize that I have crappy 3G coverage in my area even though AT&T claims its all over the place. So I decide to just go back to my 1st gen iPhone. Am I still going to get the old rates ($60 plan), or will I lose that and be forced to stick to the new plans? Also wondering, if I give my iPhone to a friend/family member, when they activate it, will they get a choice of the old rates?
