Why is there no EDGE coverage in London

When I was in America. I was suprised when my little data service icon on my SPV M500, changed from G (gprs) to E (edge). Generally GPRS delivers ISDN type speeds while EDGE delivers closer to slow Cable Speeds. In actual life, I was getting about analogue modem speeds (33.6k) on GPRS and single channel ISDN speeds (64k) on EDGE. Which isn't bad, because that's about the same as I got on 3G with my Sanyo S750. But what I don't get is why there is no EDGE coverage in London? I've been around and never noticed the icon change ever. While on Cingular in America I was always on EDGE and even out here in Bristol, EDGE is available once you get closer to central Bristol. Maybe it is the 3G networks pushing out inbetween technologies like EDGE? I do kind of miss having 3G (UMTS) on my phone but having Wifi is a huge plus and I'm honestly finding more use for Wifi than 3G recently.

Talking about EDGE and America, I'm a little worried about my next Orange bill. See I didn't use the phone much for phoning but I did use the data services a lot. I was trying to arrange the @media Social venue from outside the country and needed to email back and forth. When I looked at the Cingular roaming call charges on the Orange site, it seemed to be about 10 for a meg which is a super con but I'm hoping that I never touched that 1meg limit. I mean the phone was on EDGE a lot but wasn't actually transfering any data, so it should be ok. Anyway, I'll find out within the next 2 weeks exactly how much it all come up to. I'm expecting a large one but mainly because of calls from here to the America, ironically.
