I just watched the conference and this is confusing me to no end. I owned an iPad 2 3G AT&T since Verizon was pretty crappy in my area. Would it be advisable to purchase the new iPad 4G with AT&T as well? Or would the 3G radio in either iPad 4G be compatible with both networks? The way I'm thinking the new iPad works with both AT&T and Verizon 3G towers irrespective of which model you choose, and only the bands for 4G are different. Can someone please confirm. Thanks.
