I just got a new iPhone 4 the other day. While driving through the mountains today in the Pacific northwest I noticed a lot of non-broadband areas which appear to be largely covered by Verizon's mobile broadband - at least according to VZW's mobile broadband coverage map. So if I want to switch am I going to lose my pants on this ATT iPhone and not be able to sell it for much once the Verizon iPhone comes out? Do you all (those of you with more iPhone experience than I) notice this to be an issue in real-world usage? Does Verizon really blow ATT away like their coverage map commercials indicate? Or is ATT really not that bad? Also, what does it mean when my iPhone shows an "E" at the top instead of the "3G"?? Thanks.
