How do so many people have the game early? Mine is still on pre-order status.
as pwiz already stated:
close origin-> change date to 5th February(or 8th in EU) -> disable internet connection-> start the game - > game will ask to provide origin log and pass -> enable internet -> type log and pass -> play game.
Warning though, everytime i disable my connection, its takes a lot of faffing to get it back again, my ip address seems to dissappear, and wont come back, i have to reset my router every time, then run through a few trouble shooters, and doing this everytime i want to play the game is pretty crappy.
