I've noticed ever since I got my iPhone i've heard the phrase "Talk & Surf" (in other variations too) but I've never been able to actually do it, unless I'm on a wifi network. I'm not sure why this is. Is it only me? Must I have 3G service? (I have the iPhone 3G minus the actual coverage/service unless I travel 300 miles so I'm left with edge/wifi) Does anyone else suffer from this?Or is this something on AT&Ts end? I would much rather NOT have it on their end seeing as their telling the world they can do this. Any help would be awesome now, thanks.
