I dropped my iphone in water. I need my texts. What do I do?

I dropped my iphon4 in water and put it in rice but nothing has happened. My best friend past away a month ago and I had so many text messages from her I was going to go through one day when I was ready. I'm so upset this happened and I'm freaking out. Is there anything I can do? I have no idea how iphones from Verizon work since there's no way to open them and they have no memory card slot?
