Newer iPhones slower on Edge than older iPhones?

Way back when I got my iPhone 3G we only had Edge on AT&T in my town and it worked fairly well. I could watch YouTube videos, browse the web and do most other things and the speed wasn't terrible. Since then we have finally gotten 3G in my town and I currently have the 4S which is fast and works great. On the outskirts of town you loose 3G and go back to Edge with full bars and it's virtually useless, it literally takes minutes to load a web page! Why is this!?
Is the current iOS just not made to work properly on Edge?
