Transferring everything from old to new iphone?

My iphone 4 was stolen, but i still have an old iphone 3.normally when you buy a brand new iphone, i know that when you connect it to your computer it automatically puts everything from your old iphone on your new one (contacts, pictures etc.)
But the one i want to use now has a lot of old stuff on it, its basically not "empty". When i plug it into the computer i don't see the option to put everything from my old phone on the new one. How can i do this?

I dropped my iphone 4 in water?

I dropped my iphone 4 in the toilet bowl for about 5 seconds. It was fully submerged then i took it out. It was flickering then it turned off. I searched online on how to fix it. It says I have to put it in a container of dry, uncooked rice. So I did that, for 10 hours. I took it out. It was able to appear on iTunes. I restored it and right now everything is there… There's just one problem - THE SCREEN WON'T TURN ON! Everytime i press the home and the lock button simultaneously it gives a beep vibrate type of sound… Anyone know how I can repair this! (other than taking to an apple store)
