Guys, a quick question. The "@" button on the right side resembles Internet button right? If I were to connect to WiFi and press "@" button to surf the Internet, will it be counted as WiFi or WAP?

I seem to be charged for that, I thought I have successfully connected to WiFi.

I seldom use my phone to surf the net, the globe sign will appear when I connect to the Internet regardless I use any type of connection? (i.e. WiFi or GPRS)

Please help to clarify, or I must use Opera when I connect to WiFi? It seems like I have problem with my Opera hence I pressed on "@" button and got charged later.
