This is the best fix I've found to repair the greyed out wifi for customers that have upgraded to any version of iOS7. Whether it sounds silly or not it works! Mine has been up for months now! This phone has been on every single version of iOS 7. Each upgrade has killed the wifi and each time was fixed with this technique. The freezer fix is only tempoary. The chip must be reset with heat in order for the iOS to read it correctly. This is a permanent fix until you upgrade again!
