I upgraded to the 3GS when it came out and enjoyed the increased speeds. However, sometime in early December, I couldn't get online at all for a few days which, after calling O2, turned out to be problems with their network. Since then, although I can now get online, I don't think I've seen the '3G' symbol since before that time - getting on for two months now. It's painfully slow and, most of the time, I've just got the GPRS circle or, sometimes, Edge. I'm in SW London - is anyone else getting any 3G reception?
