Ok, so I have a question. If I have iOS 5 installed on my iPhone 4 and have everything backed up to iCloud prior to getting my phone tomorrow...I will just be able to activate the 4s right out of the box, correct? And if so how will the 4s know my phone number? Will I take the sim out of my iPhone 4 and put it into the 4s? Because a thread I read earlier said we wont have to worry about swapping sim cards at all.
