I just ported over to T-Mobile and took my iPhone 4S with me. Those prices cannot be beat. Now where I am at (Outside of Indianapolis), I am only on Edge, but I really don't care, T-Mobile's Edge actually works better than AT&T's. I have been able to stream audio (which I did to test it out) and it works fine. And web pages load too. I am on the $70 plan that gets me unlimited everything plus 500MB of hotspot and even on Edge, the hotspot works decent. I was able to turn it on, connect my iPad to it, and then VPN back into my office and open up a remote desktop session. For me it works fine. 95% of the time I am on WiFi anyways so the speed is not an issue for me and so far service has been good, I am saving money and get to use the same phone, I have zero complaints.
