After installing today's RC3 release of Blackra1n and then Blacksn0w, my wifi for my home network went away on my iPhone - nowhere on the list under settings did it (or any other wifi network for that matter) appear. I Googled and found one post that said I should reset my network settings. When I did that, the tethering that the "black st0rms" had turned on was gone. I'm now performing my 3rd restore to try to fix things so I can have wifi and tethering. Has anyone else run into these issues? Any advice?
