Since sometime around having 2.2.1 firmware I have been unable to join my schools wifi network on my 2nd Generation iPod Touch. (I am currently running 4.0). I was able to join the network for a month or two then randomly I could not. I would get to the page on my ipod where you enter in your username and password for the network but my ipod would not type anything into the fields. I was clicking on the letters but nothing would happen. I need help! School is going to be starting tomorrow and I would like to be able to use my ipod touch on the wifi.
