I agree with the thread creator, Sprint just sucks in Springfield. I live just outside of Springfield and the 3G data has been horrible for at least a year on the south side of Springfield. Even though I may have 3 or more bars signal speed tests regularly show my ping at or above 1 second (that's right 1000ms) and download speeds below 30kbps. That's pretty much the entire south side of Springfield, MO. LMFAO I live about 180 miles from the Sprint HQ.
My wife works on the south side of town and has given up trying to use her phone to do anything other thank voice and simple SMS during her 8 hour work day. We have both tried (repeatedly) to browse the web, use apps or send MMS and nothing happens. This is on an almost daily basis for almost a year. I had to laugh when I went to the Sprint Corp store (with a tower strapped onto its backside) on the south side of town and I still couldn't pull down a webpage, go the Market or sent an MMS. Download speed was sub 20kpbs and pings were between 850ms and 1000ms.
I'm not even worried about 4G. I don't have a reliable 4G signal anywhere near where I live and even when I travel to larger cities, which I do all the time, with it I rarely if ever get a good signal in the buildings or hotels I stay in. I had to laugh when a few weeks ago I had a job that took me to the Plaza in down town Kansas City. That's about 15 miles from Sprint's Headquarters. And while I could get some 4G while walking around outside. Yep forget it inside. LOL 15 miles from home base.
I guess the answer I'm hearing here is suck it up, pay the money and use WIFI...
