I have a blue box with a white E inside most of the time, but the network seems very slow. I am certainly not getting anywhere near the sorts of speeds that people say EDGE should achieve. It is SLLLOOOOOWWWWWWW.
410 kbps according to the site. Seems slow as molasses to me.
According to this site, that speed is very good. I wonder if it is not the EDGE connection, but O2's handling of Internet transactions on their side that is slow.
