Quick question: When I look at ATT's coverage area it shows I have moderate coverage, which is accurate, but when I click the icon to show 3G coverage it says I have full coverage. I bought the 2g iphone a couple months back but the moderate coverage was not really sufficient for use in my house so I returned it. My question is, because the new iphone is 3g is there a chance my coverage will improve or is 3g only pertaining to data services?
