My Captivate went through the washing machine. On month 4 of my 24 month contract.
Disassembled as much as I could, dried it out for a few days, and it powered up like a charm. Even made phone calls and data, but the battery died in an hour. Replaced the battery and all works well, with the exception of WiFi and Bluetooth. Tried to get it fixed, but several repair folk told me that the wifi and BT chip are part of the board and could not be replaced. 3 of these repair shops told me that it's only a matter of time before the phone stops working. Well, that was well over a year ago and the Cappy is still going strong.
Will be replacing it soon enough with a no-contract Galaxy Nexus. It was good while it lasted
