Change everything from one iphone to another?

Ok so I have the iphone 4 on iOS 7 but I just bought the iphone 5s also iOS 7 I was wondering if I can backup my iphone 4 and put it on my 5 but i don't know how and my computer is on the iOS 5 version

I'm also wondering if there's a way to change one phone to another, let's wait nice to answer this question.

Yes you can transfer the data from your 4 to your 5s. Just back up the data from your 4 on your iTunes. When you plug in your 5s, you can restore it the latest backup on to it.

Yes. I think there's a reliable way to sync your old iPhone data to the new one, see detailed info on: http://www.imobie.com/...iphone.htm Good luck.
