heya. im having this problem on my ipod touch 2G with 3.0 firmware. before(on 2.2.1), the wifi is pretty fast and easy. but now,even though i can connect to some wifi networks, internet stuff is simply impossible to me. i dunno why. it says its connected to the network but i can't do internet stuff. for example, safari always say "can't connect ect" cydia also can't load or update or whatever. i can't do ANYTHING internet related. >.< help please..
