I received my iPhone yesterday and used the iTunes 7.3.0.54 activation trick. That worked fine. I was able to use WiFi with no problem. When I tried to use iBricker it used the 1.0.2 firmware that iTunes downloaded. That also worked fine, however, now WiFi does not work at all. I've tried different networks but the iPhone does not detect anything. I even tried to restore through iTunes.

Anyone have any ideas?
