I'm seeing a bunch of reports on here that Sprint is slower than AT&T for the iPhone but where I live (way out in the country) I'm having a terrible time with no internet and dropped calls. My Mom came to visit from Wisconsin (I live in Texas) and she was using her US cellular tethering and it was much faster Internet and better reception than my phone. Heck, the tethering was faster than my WildBlue Internet! When we called US cellular to find out what tower was being used they said it was a sprint tower. So I was thinking to switching to sprint if it worked that much better. Any experience?
