ChkWebSpeed is FREE utility we have made available. It reports the real download speed of any website's page on your Mobile device over any wireless (WiFi or Cellular) network. It is the same speed you would experience if you were to browse the same page using your web browser. What's cool about the utility is that, it provides the graphical view of download speed of webpage over subsequent 10 iterations and then provides min, max & avg. over those 10 iterations. Currently this utility is supported only on iPhone.
You can add your favorite website URLs to the URL list maintained by this utility & then check out for real how fast those websites are at any given time on your Mobile device. This is really useful especially when you are having trouble with one particular app say "foo" & you need to confirm if its really network which is bogging down that "foo" app. In such cases just launch ChkWebSpeed utility & check if accessing other websites is also slow or not. Also if you know that "foo" app accesses say http://something.foo.com then you can try out if accessing that website in ChkWebSpeed yields the same results or not.
Also more importantly using this utility you can find out the sweet spot at your home or office where accessing websites is faster.
