I don't trust the site you posted Chris. I just tested on my Work PC and I first clicked on the High Speed :
Then I clicked on the mobile:
and then back on the highspeed:
And once more on mobile:
It's all over the place. I continued alternating between the 2 and Mobile is always reporting slower than the highspeed From my PC, even though it's the same connection.
Just thought you should know that there might be something "iffy" with that test.
Testing from my iPhone right now:
180kbps and I haven't moved my phone.
BTW, the first number it gives it not the test results. It keeps updating. Wait till there is "verbiage" under the results.
