Help!!How backup iphone 3GS sms/contact to my new iphone 4?

[summera]

I'm a student from a college,recently I bought a new iphone,but I meet some problems.So,I want some advice.
The problem is that I am trying to get my SMS,contacts and pictures on my iPhone to be put either onto my computer or onto iTunes and I don't know how to do this.
Any help or advice would be greatly received.
Thanks in advance.

iTunes will back them up for you, SMS, Contacts etc. just use it to 'backup' your 3GS, and then restore to the iP4.

But save your pictures to a separate folder anyway just in case.


I'm just waiting for the inevitable "How to back up your iPhone SMS's" spam post by the way....
