So as you all know, apple said the iPhone 4s would get faster data speeds if you're in the right area. I'm coming from the 3gs and let me tell you, I'm getting faster downloads and uploads for sure. It's crazy how much faster it is than the 3gs in every way possible. When I activated my 4s, I called AT&T to make sure that my data plan was still unlimited and she said I'm on the "4s data plan" and she also said I will love the speed of the data in my area. She wasn't joking. I'm loving this phone!
