Help

Had a iPhone 4 in my pocket, when I was pushed into a pool. It was in an otter box, but still it's not turning on. It's in a bag of rice now. I have an older iPhone 3 that I activated, but when I sync'd it back to iTunes, the app "Photo Folders" was reinstalled, however it didn't sync any data in that App. All my folders, and pictures in those folders are not there. Any suggestions, any ideas to try and recover my pictures? Thanks for the help. JR
