Wet with water and does not starts

Ashwini Raj, the very first thing you want to do is to stop trying to turn your phone on or try to charge it etc. you need to disassemble it. Use this document ==>>A310_Disassembly_Procedure.pdf<<== to help you with that. Once you have it disassembled, you need to clean everything with a high grade isopropyl alcohol and a small brush. Use this guide to see how it is done. It was written for an iPhone 3G but all the points are still pertinent to your phone as well. Once you got it properly cleaned, replace the battery reassemble and re-evaluate for any damage.
