1991-C4 - out of curiosity, what is your connection speed meant to be? Your results suggest an actual speed similar to mine if its accurately inaccurate (if you get what I mean!).
Sweetpoison - in answer to your last question.. It's not that clear what it is using, but you can figure it out. If you have both wifi and cellular data enabled - from left to right you have your cellular signal strength, your service provider, and then either a kinda upside down triangle with a curved top made of three bars (full wifi strength with 3..) - if your accessing the net with that displayed, you're on wifi; OR "3G" or a little circle - which indicates your using your cellular data plan to access the net.
If that's not clear, I'll grab a couple of screen shots to illustrate.
