heya. so during my class,out of boredom, i just checked my itouch for anything. i checked the wi-fi and found out that there's a connection. so i joined successfully. but the thing is, i can't do internet stuff like browse safari or chat with y!messenger. safari just keeps on saying "safari cannot open the page.." see, i'm "connected" to the wifi but i can't actually use it.. come on! it's like im not connected to any wifi connection at all.. any suggestions please? p.s. this ain't jailbroken. it's 2.2 @ that time..
