What, other than carrier performance affects data speed? I was at a friend's house. He has an iPhone4 on ATT. I have the Epic on Sprint. We did simulatneous data speed tests using Speedtest.net. My Down/Up results averaged .40/.24 and his were 6.2/4.0 with one being 9.2/8.6. We have unadvertised 4G here. It is not available where we were at, but later I went to a location where I can connect to it. On 4g my results were 2.5/1.1 I've run this from various location around town and based a sample size of 20 I average .591/.207 Just pathetic. Before I completely blame Sprint I'd like to confirm if the difference in processors or maybe data storage amounts could have anything to do with my ability to download data or is this really just want I think... Sprint sucks here. FWIW - I have 7.32GB free of 7.41 Available on my SD card and 156MB of system storage available. Is it all Sprint's fault or is my phone skewing the results? Thanks!
