Hi, is there some issue about activation ? here is what i did, i can't use my at&t paygo sim at all ! 1- freshly installed 3.1.2 from itunes (it was with older baseband under 3.1.2 using quickpawn) 2- Legit Activated with my carrier in canada (rogers) (i don't want to lost my push notification) 3- installed cydia + blacksn0w 4- restored from backup my setting, mp3 e.t.c 5- All work fine except that when i use another sim the different sim pop up on my iphone and i can't activate it using itunes... I am gonna try with a different sim from service in canada soon, maybe its because its a paygo service and we can't get service in canada ? let me know if i did something wrong !
