Path is like this: Mobile Borwser -> Opera Proxy -> Target Site Depending on Site, stats companies capture it at Layer 1 routers of major providers like NTT or others like Gawker send daily feeds to it. Opera proxy reports UA as Opera Mini. Layer 1 is something like telephone exchange. Regarding 6303, it has two browsers. Depending on which browsers you are using (Device or Opera) it will send different strings. Run a simulation on Nokia's test baords, you will get a list of All UA's reported by a perticular build of OS (In this case S40 firmware for 6303). UA (User Agent) is part of HTTP headersent by client. Based on this, this phone has both WebKit as well as Opera. WebKit is default. So if you use things like Google Maps app, web panel in that App would use WebKit.
