hello i am from france my iPhone 4S fall dow into the water. now i can’t switch on. is there a chance to repair it. do you do that? is the logic board damaged? regards

jean christophe, the first thing I strongly suggest is that you disassemble your iPhone. Use these guides to work on it. After you have it disassembled, clean all the parts with high grade isopropyl alcohol (90%+ would be perfect). You can follow this guide for the cleaning, it will work for your iPhone. After the cleaning replace the battery and re-evaluate for any damage. Hope this helps, good luck.
