I guess AT&T, just like DSLR forgets that people have WiFi in may spots. My EDGE iPhone was slower to load content on EDGE but when I am home I use WiFi, when at work I use WiFi, when I'm in many business locations I will use WiFi. On the 3G iPhone I only use 3G when I'm in locations that I don't have WiFi access (less than 10% of my usage). In fact, the whole reason for me to upgrade my phone was to have more storage (8GB -> 16GB phone).
