Ah okey... But depend on what phone you are currently using, there are softwares which can help you to transfer your contacts from your old phone to your new iPhone. As for the pictures that's not something to worry about. It's easily transferable from your computer to your iPhone.
just like me when I first hands on the iPhone 4. I couldn't put it down for 1h unless I was tired of looking at the screen and having a rest. It's a lot addictive.
