Hello all, I just have a quick "out of curiousity" question for everyone: on the iPhone there seem to be three possible data connections - two of which are the 3G network, represented by the little 3G logo beside the carrier name, and Edge, represented by the "E" symbol. However, on a trip to a rural area, I noticed a third symbol - a blue box with a little white circle in it. Does anyone know what the name of this data connection is? It was very slow, so I'm just curious... Thanks in advance!
