So i've owned the touch for at least 3 years, finally jumping on the phone bandwagon and had a couple of noob question on the iPhone in general Can you change the Text tone and ringtone and customize it for all your contacts? What about pictures for contacts? This is my first phone on the At&t line, when I get the phone how would I go about activating it? do I get to choose the number? What kind of things can you ask siri? I've been seeing a lot about people unlocking phones. What does this do and how does it benefit me? Thanks if you can answer, really hyped to get mine friday!
