After upgrading to 3.0, 3.1 with pwnage, my wifi has disappeared. In general: about my wi-fi adress is listed but i can not detect any networks. Any suggestions???

Try going to settings and reset, then reset the network settings, my iphone was actually saying wifi disabled, and I reset it, then it came on and worked fine...
