syncing iphone without internet connection
so if i take my computer to another house and plug it in to the internet, i can activate it that way, right? we currently have an ipod (and itunes on our computer), but the only thing i would need the internet for on my computer in the future after activation is to update the iphone software, or restore the iphone? will i still be able to sync the iphone with itunes (just to update the music, videos, etc.) without connecting to the internet?
