How to restore data on my new iphone?

So I ruined my iPhone 4 in the water, so now I got an iPhone 4s. I had made a backup of the 4 before it broke, but when I restored this backup on the new iPhone 4s, it deleted all of the current conversations I was having over text. Is there any way I can get those back?

I have problem as you, I searched on google on few days and I find out a successful method.
