I am kinda over these threads. yes it could be automatic or not. I drive through three cities on my way to college, living in so cal you know how it is, but still, with in that 20 mile radius, I get speeds from 300kb all the way up to 2.5mb, yes it is the network. If it was the phone it would not be hitting different speeds in different locations. The network might just suck in your location. At home I range from .75 mb to 1.5mb, Yes sometimes during the day I get .4 or .5.
as I was typing this I hit 1.39 and 1.62 download on 3g, I wouldn't be surprised if they go down dramatically in a few hours.
