Answer to: Wifi can't find networksso here is what worked for: you need to go to settings and reset network settings. then power your phone off. put your phone on a zip lock back and put it in the freezer for 10-15 min. then power your phone back up, it should be fixed. It may last a couple of hours first time, so you may need to repeat it. Also, i have read somewhere that the router security settings (WAP/WAP2, etc) may prevent iphone from connecting to it.
