Like tonight for example, we were at a concert (Coldplay lol) inside an arena... I was on "E" the whole time inside the building, and couldn't do anything (email, or even send a damn text). She was on 3G and could do whatever she wanted. We both have an iPhone 3G, only difference is mine is 16gb and her's is 8. We're on the same plan... How is that even possible?
