Everything is OK but i'm not able to find "Wi-Fi Only" check in settings menu/software updates.
In the Software Updates menu there are only 2 voices: "Update" and "Automatic Update". Nothing else.
I had previously flashed the 4.1.1 nobrand Spain version and was ok, then I flashed 4.1.1 nobrand French version that had the same problem as the UK..... I don't understand if there is something wrong in my device... or if they deleted these option of upgrading through 3G network, too.
Can a wipe data resolve?
