I am running Belgium ROM (Belgacom/Proximus) and my green square 1x1 'software update' widget shows a red circle with N inside.
I guess this might mean there is a new ROM. But, on SamMobile, I do not see one for Belgium.
Also, software update (correctly) complains my device is modified.
Has someone else lately done an OTA update in Belgium? If yes: what does calling *#1234# show?
