If by unactivated you mean not yet connected to iTunes then absolutely nothing.
I mean not activated by AT&T. This will be a new account from a ported number which won't port until I activate the phone. I am just curious what i can do with it before I activate my phone number on it. I would assume it will still connect to itunes without having the phone number activated on it.
The phone will work for everything except 3G data and cell service. So you'll be able to do anything on wifi, even use skype to make calls.
Awesome. That is exactly what I hoped. Though I bet Facetime will not work without the 3G activation (even though it doesn't use it).
That is entirely untrue. Don't listen to redbotsoftware.
Now I am confused.So without it being successfully on AT&T's network, it cannot be used on wifi?
Jimmy is right. If it's a brand new phone, it's not going to work until you plug into iTunes and agree to your two years.
A phone bought of craigslist or ebay, however, will be fully functional (minus cell service, of course) without having anything to do with AT&T.
