The second update to Apple’s so much rumored iOS 6 has just been released, with a single-sentence description by the Fruit Company: “Fixes a bug that could impact Wi-Fi.” So to see if the update bringing solution to a problem with Wi-Fi connectivity has rolled out to your device as well, navigate to Settings > General > Software Update.
iOS 6.0.2 takes approximately 20 minutes to be installed on the iPhone 5 completely, and then a reboot is necessary for the upgrade process to be finished.
The security notice published by Apple back in October read:” In rare instances, your iPhone, iPad, or iPod touch may be unable to enable Wi-Fi or Bluetooth in Settings.” Numbers of users have been left without easy access to Wi-Fi, repotting to have seen a grayed out dim Wi-Fi or Bluetooth setting, while others complained about the missing Wi-Fi or Bluetooth MAC Address or a device that displayed all zeros in Settings > General > About.
The only recommendation Apple gave till today was to restore their network settings to rectify the Wi-Fi bug, along with a bizarre tip to put the iPhone in a plastic bag and put it in the freezer for 10-20 minutes.
The previous iOS update 6.0.1 was rolled in early November, with small glitches still present, such as the onscreen keyboard and camera flash. The iOS 6.0.2 is available OTA (over-the-air), so keep checking settings for an upgrade notification.
