Wi-Fi greyed out (no Mac Address), Bluetooth not working either
The Wi-Fi on my iPhone 4S (6.0.1) is greyed out and Bluetooth is not working either (being busy forever). This happened somewhere in the past few days.
I tried Reset Network Settings and Restore to factory defauls (using iTunes). Nothing works.
Settings -> General -> About -> Wi-Fi Address shows N/A.
Please help.
