My Iphone 4 will not turn on and i do not know what to do?

I had got a very little bit of water into the top of my iphone and it would not do anything. I quickly searched the internet and figured out that if i put it in a bag of rice and let it sit that would work, so i did it, and the next morning my Iphone was working great. It has been working fine for about a week now. Today i took my phone out to the check the time and it would not turn on. I can't get it to do anything. Should i put it in the rice again, or try something else, i'm really worried my iphone might be "dead" for good, so please help me!

Added (1). I've tried charging it can't even get the apple logo to come on

Charge it…

It may be some tecnical problem. You can make sure by chaching you phone by any proficient person who can fix i phones.
