can i use the iphone by jus putting surrounded by my existing sim card in and lacking signing up for other stuff?
Answers: The phone itself is $399 via the Apple Store. Once you purchase the phone, it's up to you how you'd like to set off it.
However, you cannot simply pop in your own AT&T sim and expect the iPhone to work. It won't. The iPhone requests to be activated via iTunes where on earth you'll be able to choose your plan. If you already enjoy a AT&T plan, you can upgrade it for iPhone use and move your phone number to the iPhone.400
