So I've been bumming out thinking my AT&T HSPA+ speeds were just horrible. And they may be. But I noticed in doing my tests with the speediest.net app that no matter what data network I'm on, 3G or Wifi, I get bad speeds. Especially compared to what I see other people posting in the forums. I just did a test, and got the best speeds I've ever really gotten. At home, my wifi is connected to a 25Mbps cable modem. My Macbook Pro runs the test at speedtest.net and gets a result of 35Mbps down and 3.12Mbps up. Yet on my iPhone 4S, it tells me I get 3.27Mbps down/2.34Mbs up. On 3G, however, I never see over 1.5Mbps down and 1Mbps up. So I'm not happy with speeds I'm seeing anywhere. Yes, my AT&T plan says it was the DataPro for 4S, so I think it is correct. And as mentioned, speeds on wifi suck too, so maybe it's my phone? What should I do?
