Nicole, the problem that you might run into at this time could range from corrosion on the logic board to a bad battery. that is way it is so important to clean the phone as soon as possible after any water/liquid exposure. You did not give us the particulars about your phone, so I can only give you a generic answer. On this page you can identify your phone and select it. Look for the guide that will show you how to perform a logic board removal. Once you have your phone apart, clean it using this guide. Once you have it all properly cleaned, look for any obvious damage. Once you are satisfied that your logic board, cables, and connectors (do not forget the dock connector) are cleaned,replace the Battery. I believe that this is the root cause for your phone failure. Once you replaced it, reassemble your phone and re-evaluate for any damage, if any. Hope this helps, good luck.
