Apple this evening has flicked the switch to release iOS 6.0.2 update to its mobile OS. The release is aimed at iPhone 5 and iPad Mini.
Fixes a bug that could impact Wi-Fi.
Applying the update to your device is easy. Settings > General > Software Update > Install, that’s all you need to do.
Are you having issues with the Wi-Fi on these devices? I’m not.

WiFi on my iPhone 5 has been pretty poor compared to my iPhone 4S. Since upgrading my iPad 3 to iPad 4 the wifi is also not great. Hopefully this update will address those issues.
My iPad 2 has got problems since I upgraded to iOS 6.01
