Mpho Leboho you treat this just like any other submersion. it is a bit of a guessing game as in how your phone will respond to a proper cleaning. The importance right now is to not turn it on, or trying to sync/charge it. Remove the battery, and disassemble it by using [guide|45850|this teardown] carefully . Clean everything with isopropyl alcohol (90%+) and a soft brush, including all connectors and cable ends. Clean it properly using [guide|5825|this guide.] It was written for a iPhone 3G but all the points still apply to your phone as well. Remove all EMI shields and check for any burned or missing components. You may have to repeat this step a couple of times. Once it is cleaned, reassemble it and ''' replace the battery''', then reevaluate for any real damage. Right now, everything will only be a guess, and the longer you wait the more corroded it will get.
