I've only managed to get the 3G icon up twice on my phone (over a period of a year and a half)
These have been at:
1. London
2. San Francisco
Not EVERYONE gets 3G, my phone constantly says 2.5G, it has NEVER gone to 3G apart from in London, I'm on O2 as well, which Apple will hopefully go with.
Well, on o2 with my old W850i the 3G icon was always up. Although it wasn't as fast as it should've been.
Being realistic, the 3 network over here are going bankrupt. If Apple were to release a 3G iPhone, 3 would do everything in their power to get it.
It'll be EDGE.
If its 3G I'll eat my PowerBook.
