i have this iphone with the firmware 1.1.1. when trying to do the unlock, the wifi keeps turning on and off. i would see my AP and then as soon as i join it turns off then won't connect. I then try to reflash the firmware and everything is fine but still the same problem. it seems to me that phone wifi part is damaged. i am trying not to bring this back to apple in the fear that they will replace this with an OTB 1.1.2 firmware phone. any suggestions?
