This is a tweak that displays whether or not there is internet access available using an icon in the status bar.
This is useful in case cellular data is enabled but it can’t be determined if there is internet access or not, or if there is a wifi connection, yet no access to the internet. Compatible on iOS 8. Untested on prior OS's but should work properly.
The tweak's settings can be changed in order to change the host the tweak checks for accessibility (in case google is blocked in your country), or to change the interval the host is queried within (for battery optimisation).
