We’ve heard talk about both activation of the iPhone 3G in-store at the time of purchase, and the possibility for some people to complete their activation at home. While we still don’t know the official details, an Italian news site seems to think they know the answer. It’s actually both.

According to the rumor, half of the activation will be done in-store. This will include activation of the phone with your carrier, and choosing your rate plan. Once you get home, you’ll need to use iTunes to set up billing information so that you can purchase and download programs via the App Store.
