They sent me an Wifi AP WRT54G, which modded by Fon Firmware.
It says today,
>> Hi Ryu,!
>> You are the # 46593 member of the FON Community, and you're linus
It redirects to FON authentification web page when I connect to Internet vi this AP.
I typed some information about my AP, and it made me free to surf the web.
I hope I would enjoy Wi-Fi around the world, including Capital Hotel in Bejing and Grand Palace Hotel in Tokyo.
