Okay I'm gonna explain this with as much detail as possible. I have an unlocked iPhone 4S that I am using with T-Mobile. Sometimes at random (mostly places where my signal is weak, like the outskirts of town) the carrier switches from T-Mobile to AT&T and it says 4G. It was an AT&T iPhone before I had it unlocked. I'm pretty sure it's impossible to get 4G on a 4S. When I tried to load a page or anything using data, it would not load and it would give me an error. But I was able to make/receive calls. After a while it went back to normal and the data worked again. I'm just wondering what is going on. Any help would be appreciated! Sorry about the carrier changes, I was using Zeppelin.
