IF SO: then just make sure your sim is in it and turned on and plugged in and itunes on and connected to the internet.
IF NOT: then you cannot activate it yet. There will be an unlock program coming soon so you can activate it then. Dont ask when as there is not a set release date for the unlock.
I'm with AT&T but I bought it from someone. It was still wrapped and everything. I plugged it in and synced it and it never activated the microsim. And I cant out my old sim in there
Well heres the thing. When u take it to att to get a micro sim for your old sim make sure they domt try and make any changes to your plan. Thats the important part
