My wifi was working this mornign when I was on firmware 2.2 on my iPod. Even after I upgraded it to 2.2.1, it was running smoothly. Now it's jailbroken, and the wifi doesn't work. I know I am inputting the pw correctly, and the wifi symbol (I think) at the top left says that I have a good connection, but I can't connect to safari. I tried other threads but they couldn't aid me. help?
