For the iPod touch do u have to pay for internet or can you just be by a server, i already hav dsl on my cpu?

i have a ipod Touch, it uses wireless internet. If ur by a wireless router like in my house, school, or at Starbucks you just connect to the wireless, and it works just like a regular internet browser, you can go on myspace, facebook, and even watch youtube videos. I always watch videos in cl, pretty funny
