I can't download anything big over my mobile network. If I connect to wifi, it works fine, and additional game data downloads (when you run a game and it asks you to download more data) work fine over carrier, but anything else through the market or from the browser doesn't work. It just hangs and says "Waiting for network". Now, I have a hunch this is some sort of limit imposed by tmo, but if that's the case, how do I get around it? I am paying for unlimited data, I want to be able to use it effectively!
