Most phones that i have worked on have had removable cameras. Sounds like water may have gotten in the camera assembly or not allowing the phone to make connection.

note: go with the insurance. This phone fell in the toilet. ewww. This is the same phone you keep by your mouth and ears? icky....

Brittany, it is very likely that this error is strictly caused by the camera. After all, it is the only thing that is not working. I would disassemble the phone, clean it properly. Use this guide for the cleaning. It was written for a 3G, but everything still applies to your phone. Rice is a great first aid, but it is not a permanent fix, nor will it prevent corrosion etc. After that, check your connectors and your cables carefully. Make sure they are not torn, bend or corroded. You can now also replace the camera, by using this guide. I am sure it is a lot cheaper than your deductible, and there are a lot of worse places your phone could have fallen into. Hope this helps, good luck.
