iPhone 4 fell in water
iPhone 4 was in water for less than a minute. I dried it in rice for 48 hours and it was not working. When plugged in a battery shape with a few red lines appeared and it started up but continued searching for service and would not connect to wifi. After searching through this site I got the phone apart and removed the battery. Only the bottom water sensor was red. I left the battery out over night then cleaned it and the cell antenna with rubbing alcohol and put the phone back together. It was working fine for several days then it just shut down. Once plugged in it went back to how it was after during it out and changed the date. I tried repeating the steps I did before and it didn't work. I was wondering if anyone could tell me what to do. If there is anything that may need cleaned or replaced or if the phone is past fixing.
Is this a good question?
