Sorry if this has been covered before, but how are others finding the o2 reception? Both at home and at work I find the signal varies drastically, going from No-Signal to nearly 4 or 5 bars. All this when I am in the same place. Our house has thick stone walls and work is brick and concrete, maybe this has something to do with it. Does seem strange how much it varies, don't understand that. Also have yet to see an EDGE signal yet although with a good reception GPRS is faster than I expected. Anyone else seen an EDGE signal yet and how much faster does it seem?
